I feel uncomfortable and don't want to hug an autistic person at a convention
Why don't you want to hug an autistic?
It is just that I feel uncomfortable around disabled people.
While you can set your own boundaries on who wants to touch you, it is horribly wrong to judge and treat someone else differently when they are disabled. They are human just like you and deserve the same amount of respect, you shunning them like this makes them feel like trash.
People shouldn't feel uncomfortable when I don't understand their condition.
Autistic people still have feelings. You would make them feel bad by saying they make you uncomfortable.
