My DS has AS and a speech disorder, he can be decidely 'odd' at times, but is mostly a friendly, kind, polite (well there's rules about that, lol) boy who's massively intelligent...can't find one thing in an empty room and has been known to lose his shoes at school, but that really only affects me, lol. He has no behavioural issues, isn't an objectional person to spend time with but is noticebably not an average typical child.
He stopped being invited to classmates parties at age 6, by the time he left primary school he spent break and lunchtime helping the janitor and ate lunch alone. Not through choice.
At secondary, he's had his shirt urinated on during PE, food that he's made taken off him and urinated on, he's been punched, slapped, kicked and hugged when they realised that would upset him. He's had his ear folded into a bulldog clip ( the kind for keeping paperwork together not some obscure playground slang) he's had groups of pupils follow him home so that they can play sone sort of game involving smacking him on the bottom on they way home. And of course lots of low level name calling and teasing.
I've had to explain to my DD what, mong, retard, spaz and downie refer to after she's come home in tears because she's been targetted as his sister - just randomly as she's still in primary and the children concerned are at DS's school but two years younger than him.
We're regularly told at parent's evening that DS should try to fit in more - you know, because even though his AS makes that difficult he's clearly just being awkward 
We've had teachers tell him he should make more effort to speak clearly and write better, obviously 9 years of speech therapy, 4 yrs of occupational therapy and 10 yrs of handwriting programmes at school just wasn't enough effort.
He was told that he couldn't do home ec even though he enjoys it and is good at it because he's physically incapable of lifting their biggest pan when full of water and it might come up in an exam. (obviously I corrected that)
We've had random adults asking me while out - as he stands beside me if he's not right or has special needs - for no reason at all that I can understand other than nosiness. They completely ignore the fact that he's right there, can understand and often was in fact in the middle of having a conversation with me to satisfy their curiosity.
DS has come to the conclusion that most people are unpleasant, I'd love to correct that opinion, but overwhelmingly the evidence is that at best they're ignorant and uncaring.
DS is pretty amazing though, how he gets up and goes to school quite happily astounds me, but he does and he still is willing to try to be friendly to people he meets even though he's usually rebuffed - he's great, more and more though I find myself not convinced that people in general are :(
