Probably not. Your rules are just stupid if the one you mentioned here is any indication.

Your roommates are not concern trolling. Autistic people generally have a hard time trying to accept rules that don’t make sense to them, and will question why they exist.

To be completely honest with you, the rules you mentioned don’t make any sense to me, either. Are you sure these people are your roommates and not your tenants?

No, it has nothing to do with autism. Any reasonable person would ask about the rules. Autistics will try to remember and follow them, assuming it’s just another thing that they don’t understand. Neurotypicals have probably networked and blackballed you, which is why your tenants (they’re not roommates) are autistic. NTs are also likely more aware of their rights as tenants, and would probably fight back. You’re getting off easy.

You’re also a massive tool, in case that isn’t clear.

You don’t let people eat in their own rooms that they rent?

Maybe have fewer asshole-ish rules that even “normal” people would find confusing.

If I see a plate in their room, they’re getting fined for eating in there.

I’m not sure that they’re the ones with the problem.
