People seem to misunderstand Chris' relationship with autism. When Chris is talking about windows to hell, he's talking about severely handicapped people. Like people who require 24 hour care and shit themselves. Those kind of people are never fun to be around.
When normal people deal with handicapped people, they act polite and friendly. Chris doesn't have this raging hate for autistics that people seem to think. His feelings about handicapped people are very normal. It's just that he's a giant asshole who can't keep his mouth shut about those feelings.
