"Still, haven't we all been raised to be accepting of other people"

No. As someone with Asperger's, I can say 'we' really, really haven't. There really are only three options - learn to control your body language, tone of voice etc so that you are playing by the rules most people in your society are playing by, accept that most people will dislike you if you're slightly different and concentrate on being friends with only other 'different' people, or be desperately unhappy.
