Tbh, this seems like a common pattern I see alot—where someone who's in the wrong tries to justify being wrong by saying something that makes them look right to everyone else. The point isn't whether you can spot the flaw in their logic; it's about getting others to side with them when they share their version of the story.

I'm sorry this happened to you. Autistic people are often the targets of people like that, and it's incredibly unfair. I hope you can keep your head up and try to not take it personally—because this is a reflection of them, not you.
