No, autism is an insult to anyone, and not brony specific.Autistic is now like retarded, in that it's a mental disability that's being slung around like an insult.

It's being used more for bronies, then anyone. 

I see people even with a avatar of a pony who people assume is a brony being called a autistic person, because they assume they are a brony.
