Here is a list of #autism traits that are frequently misinterpreted as "bad behaviour" (short thread):
Firstly, stimming. It's misinterpreted as a distraction and bad behaviour but it actually helps them to concentrate which is the opposite of a distraction. #ActuallyAutistic /1

Lack of eye contact is commonly misinterpreted as bad behaviour but people commonly don't acknowledge that just because an #autistic person isn't making eye contact, that doesn't mean that they aren't listening. #autism #ActuallyAutistic /2

Meltdowns are commonly misinterpreted as bad behaviour because of how they are presented (screaming, shouting, crying etc.) but in reality, meltdowns are a reaction to an unbearable sensory environment and this isn't bad behaviour. #autism #ActuallyAutistic /3

It's not bad behaviour if an #autistic person asks for someone to slow down the speed at which they're speaking at. It's a shame this is also commonly misinterpreted as bad behaviour. #autism #ActuallyAutistic /4

Feeling socially uncomfortable (e.g. not wanting to talk to new people) isn't bad behaviour. #autism #ActuallyAutistic /5

Not wanting to work in a group isn't bad behaviour. It's time people stop interpreting certain personal preferences like this as "bad behaviour". #autism #ActuallyAutistic /6

Autistic people taking their time when doing things isn't "bad behaviour". Think about would you rather see a rushed piece of work that's poorly done or a slowly but accurately done piece of work? #autism #ActuallyAutistic /7

Autistic people not wanting to do something because of the sensory aspects involved in it (e.g. not wanting to go to the school playground because it's too loud) isn't bad behaviour. #autism #ActuallyAutistic /8
