I don't feel like hanging out with somebody who's autistic.
Why don't you wanna hang out with them?
They never seem to answer questions.
Some people have disabilities that prevent them from communicating well.  You shouldn't discriminate against them.
They don't have my sense of humour.
I understand your points, but if you hang out with somebody who is autistic then you may find other good qualities you like about them. Not all autistic people are the same, and you shouldn't exclude someone based on your assumptions of their personality.
