you see, NT avoid this topic at all costs
I don't think this is a NT vs Autism thing. There are topics that, depending on the environment, are taboo and not to be discussed. Figuring out these rules is confusing (or at least, not automatic) for Autistic peeps, but actually following the rules is something both NT and autistic people must do. Whether or not you call it masking, it's still something that both groups are subjected to.
