Sadly, some people think that way, and that doesn't really make them jerks, just ignorant. Some people see disabled people as a tragedy, not in an 'exterminate-them-all' genocidal way, just in a 'oh, that's such a pity' way, it's just an old-fashioned point of view. I'm not saying it's right, it isn't, but...not evil.
Kind of reminds me of my best friend at college one time. She was a very sweet girl, but holy god, was she ever an idiot. Anyway, at our college, there was a special needs basic learning unit, there were a lot of people with Down Syndrome, and severe learning problems and so on, and as I was doing performing arts, we sometimes performed some of our theatre-in-education pieces for them, so quite often they'd come over and talk to us. And my friend would be like 'Down Syndrome people are all the nicest people in the world, they're so sweet!'....and I nearly punched her. Because they're just like anyone else, some are nice, some are jerks, some are weird, some are 'normal', it was like saying 'All dyslexics are pretty' or something, it's neither true nor relevant...
eta: This is quite unrelated to paysites too, isn't it?
umm well yeah i guess so lol i just couldnt belive the ignorance of that person
