The article he tweeted in support of isn't very good, is the thing.
Neurodiversity in the workplace is good, sure. But having a mental illness doesn't exempt you from following the social guidelines that are there for a reason. I myself have borderline personality, so sometimes I get manipulative or distant. I recognise this and do everything I can to try and solve it, and if it hurts someone, I apologise and treat it like I was just a neurotypical guy. Dysfunctional mental flaws can be treated like a NT's mental flaws (pobody's nurrfect) but extrapolated a whole bunch. You aren't a horrible person, but you still have to face up to the horrible things that you might do. It's a part of the disorder, arguably the worst part, that you have to fit into social codes that, as I said, exist for a reason.
In universities, the places the article talks about, it's not like you'd get taken out for having tourette's. Some things are unavoidable and understandable. In fact most of them are. The key point is understandable. Rules in any institution should be flexible and a little context should always be applied. But if you're creating a hostile environment around you, and it's due to being neurodivergent somehow, then you should at least be told, although I agree not punished. Stealing to fund an addiction is frowned upon and little help is given, so the writer should focus on that area instead. Disobeying codes of conduct because you are compelled to or don't know not to should still be noted, and the person told, because everyone wants to be able to trust that the average person will be logical and reasonable. Improve understanding of neurodivergence in the people around you and let them know that sometimes you could lash out or be an unreliable person, or otherwise be difficult, and if they're your real friends, or reasonable people, they'll accept that and give you leeway.
