As a person on the autism spectrum, I’m often told that, as a result of poor Theory of Mind and a lack of empathy, I am remarkably intolerant of people who do not share my opinions. This is not true at all. I’m remarkably intolerant of people who do not share my knowledge. That’s something different altogether.

I mean, if I know something, everyone else should know it too, right? How can they not? Are they stupid? Yes, poor Theory of Mind and a lack of empathy means I struggle not to be a dick to those less well-informed than me.

This wouldn’t be a problem if not for the fact that I know pretty much everything. That’s another consequence of my autism – I’m obsessed with facts, I have no problem recalling information, and I care more about being right than people’s feelings. Whenever at job interviews I’m asked about my weaknesses, I reply that I’m a perfectionist and sometimes I work too hard (ha ha), and then quietly slip in that I don’t suffer fools gladly.

That’s an understatement – I don’t suffer fools at all.

Over the years I’ve learned to control it, mostly. I’ve come to understand that people don’t spend their time looking up facts and figures and memorizing them, so my favourite pastime is educating others about things that interest me and should therefore, by rights, interest all of mankind – the equivalent ranks in army, navy and air force, the reason the days of the week are so named, what distinguishes a barque from a barquentine, a brig and a schooner, and so forth. I’ve learned to appreciate that people might not have had the opportunity to come across these facts in their everyday lives and therefore I am more than happy to address the gaps in their knowledge – I’m a giver, you see.

But what I cannot tolerate – what really brings out the beast in me – is when people are unaware of things I think they really ought to know. Things that you don’t have to go and look up to understand. Things you couldn’t have missed unless you’ve chosen to switch off your brain and walk blinkered through the world. That’s when I go ‘full Aspie’.

Like when I meet someone who doesn’t know who won the Second World War. Or who the belligerents were. Or that Hitler was a bad guy.

How uninvolved with the world around you would you have to be not to know that? You didn’t know about the Arctic convoys or PQ17? Fine. Didn’t know about kamikazes or the Battle of Leyte Gulf? Forgivable. Didn’t know Hitler was a genocidal madman? Oh come on!

The reason I bring all this up is because I’ve got in a little trouble with a work colleague. She’s very nice and she does the job fine, but boy is she ill-informed about the world. I’m not sure I’ve ever met someone quite as ignorant as she is, and it is triggering all my worst behaviour.

Right off the bat, she didn’t know what Brexit is. Admittedly, nobody does right now, least of all our politicians, but you’d have to be living under a rock not to know there was a referendum on the UK’s membership of the EU, we voted to leave by a small majority, and it’s torn our country apart for the past three years. Her excuse – ‘I don’t watch the news’ – makes me want to tear my hair out, or would if I had any. How she’s avoided hearing about Brexit, when it is the dominant topic on sitcoms, panel shows, current affairs programmes and at family gatherings, is nothing short of a miracle. What next? Who’s Trump?

Another time she came in all excited to tell me she’d seen a document – no matter how many times I correct her, she seems incapable of using the word ‘documentary’ – that said autism is caused by vaccination, and isn’t that amazing? Rolling my eyes, I said it might have been, twenty years ago before it had been thoroughly debunked and is now only believed by celebrities, crazy people, and whatever overlaps there are between the two. I proceeded to tell her all about the MMR scandal, and how, far from ruining his life, Andrew Wakefield is now a feted celebrity in America with no less than Elle Macpherson as a lover.

‘Elle who?’ she asked.

‘The supermodel? Nicknamed The Body? Magazine covers, catwalks, movies, TV? Was in Friends as Joey’s roommate? Ring any bells?’

‘No.’

‘Moving on.’

The next snafu was when she insisted that September 11 was an inside job and the Twin Towers were brought down by explosives in a controlled demolition, which inspired this rant (9/11 – the Truth) a few weeks ago. In the course of that conversation, it became clear she didn’t know who Osama bin Laden was, had never heard of Al-Qaeda, didn’t know why Palestinians might be upset with America, wasn’t aware of the previous attempt to blow up the Twin Towers in 1993, had zero knowledge of how the Twin Towers were built, and thought that despite its name being the World Trade Center, it was residential. But no, she was convinced it was the naughty government that did it and nothing I said would change her mind.

Another time I discovered she had never heard of the Cold War, or the USSR, or knew that we pointed nuclear missiles at each other with our fingers hovering over the launch button for forty years. Her excuse this time gave me a nosebleed – ‘I wasn’t around then, it was before I was born.’

Yup, we can’t know anything that happened before we were born. Since I was born in 1979, I don’t know who The Beatles were; don’t know about the moon landings; slavery; the Holocaust; Queen Victoria; Vietnam; Woodstock; the Kennedy assassination; or Martin Luther King, Jr. If only there were some way I could discover information about the past, information I could access from anywhere in the world with a mobile phone signal, whether in written, audio or visual form…you can see how hard I had to work not to call her out on this bullshit!

When my manager asked me how things were going with her, I was honest. She’s a good worker, she’s good at her job, but oh my gosh I just want to scream at her for being so…I don’t know what word to use. If she was on a quiz show, I’d be shouting ‘idiot’ and ‘moron’ and ‘dumb-ass’ at the screen, like I did this evening to the guy on The Chase who thought Charles de Gaulle was from the Middle Ages. But I don’t think she is ‘thick’, for want of a better word, just completely blissfully ignorant of anything you might expect a 30-something to know.

My manager told me I had to accept that not everybody is into the same things as me. Fair enough, I said: maybe she’s just totally cut off from politics so doesn’t know about Brexit; wasn’t properly trained, so doesn’t know that vaccines don’t cause autism; has never heard of Elle Macpherson because she’s never opened a magazine; believes whatever rubbish people tell her as she has zero knowledge of geopolitics or structural engineering; and is unable to learn about the past without access to a time machine. Okay. It drives up my blood pressure, but I’ll find a way to get past it.

But I really struggled to hold my tongue when I discovered, in a conversation about the murder of Lyra McKee, that she’d never heard of the IRA.

‘The IRA.’ Blank stare. ‘The Irish Republican Army.’ Blank stare. ‘Oh my god, are you seriously telling me you’ve never heard of the freaking IRA? The Troubles? The army patrolling the streets? The bombings? The Guildford Four? The Birmingham Six? Bloody Sunday? They fired mortar bombs at 10 Downing Street. They killed the Queen’s cousin.’

‘When did it happen?’

‘Since the late 60s.’

‘Before my time.’

‘They blew up the BBC in 2001. You’d have been 14.’

‘No, I don’t remember that.’

Well, I got cross. I got cross because it frankly boggles my mind that somebody can live in this country and not know that for a period of thirty years, 3500 people were killed on our streets either for or because of the cause of Irish Republicanism. I got cross because I grew up in the 1980s, and even as a child was well aware of the risks of bomb attacks whenever I went to town, got on a train or saw an unattended bag. And I got cross because I was profoundly affected by the 1993 deaths of three-year-old Jonathan Ball and twelve-year-old Tim Parry, a boy almost the same age as me, killed by an IRA bomb planted in a town centre.

It more than boggles my mind – it offends me that somebody should be so ignorant. She will have come across it multiple times in her life – at school, on Remembrance Day, in films and books and music and everyday conversation. She knows all the words to Zombie by The Cranberries and has seen the music video, what the hell did she think that was all about? It means she’s chosen not to take it in, not to pay attention, not even to notice it, and whether it’s my autism or just me, I find that impossible to understand.

But the real bust up, the real head-to-head, came from something small and insignificant, as do all straws that break the camel’s back. It came when she picked up a roll of fly paper with the words Fly Paper on the side and said, ‘What’s this?’

‘Fly paper.’

‘What’s fly paper?’

‘You don’t know what fly paper is?’

‘No.’

‘Oh my god, have you spent your whole life living under a rock with your eyes closed, how the hell can you not know what fly paper is?’

‘Because I don’t, okay? And you having a go won’t change the fact that I don’t know what it is, so why don’t you just tell me?’

‘It’s sticky paper that you hang up to catch flies!’

And I won’t tell you what I said next. My manager tells me I need to be more tolerant of people who have had different life experiences than me. I get that, I do, but surely there are limits, right? I wouldn’t get annoyed with someone who has genuine reasons for their ignorance –  they have a learning difficulty, they have only just moved here from another country, they’ve been in a coma the past fifty years – but someone who is, by all accounts, ‘normal’ has no excuse or justification for being so ignorant.

Like I said, maybe it’s my autism or maybe it’s just me, but I cannot understand how people like this even exist – people who either don’t know or don’t care who’s running the country, don’t know about major things that are happening or have happened in the world around them, don’t even know about pop culture. What on earth do they do with themselves? What do they talk about with their friends? I don’t get why somebody would come across a word they don’t understand, or hear something referenced that they’ve not heard before, and not look it up. Do people do this? Go through life so happily ignorant that they simply skip over everything they see and hear that they don’t understand? How can they understand anything?

Let me put it this way. If you don’t know about politics (Brexit, Trump, the growing polarisation of society); current affairs (Climate Change, #MeToo, terrorism); pop culture (Star Wars, Kurt Cobain, Batman); high-brow culture (Jane Austen, the Mona Lisa, Picasso); science (medicine, plate tectonics, evolution); or history (Pompeii, the Crusades, Pearl Harbor); then what the hell do you know? And where have you been all your life? And why should I listen to anything you have to say? Because without knowledge to back it up, your opinions are worthless.

Hmm. So maybe I am remarkably intolerant of people who don’t share my opinions. Or maybe I just don’t suffer fools gladly.
