Autism doesn't excuse you acting like a daft twat. It also isn't a get-out-of-jail-free card. Autism doesn't make you do bad things.
You can't do bad shit on purpose then cry "muh autizm" and expect that to work. I say this as somebody who was *actually* diagnosed with autism by actual doctors and psychologists.
You shouldn’t use autism to cover up all of your shitty behavior, but you shouldn’t go “oh well I HAVE AUTISM” when every person’s experience with it is completely unique
