I think that a lot of people in the straight world* react weirdly to disabled people for a couple of reasons. First, they recoil at just how much effort it takes the person to accomplish some task ("Jesus Christ, that person's killing himself just to get into a chair!"). Then, the imaginitive placing of themselves in the disabled person's body leads to a further feeling about how humiliating it would be to be like that.** There might also be some instinctive recoil based on the fact that it is initially harder to discern many disabled people's intentions just from scanning their posture and face. But one of the nice things about humans is just how easily they get past these reactions, not just cognitively but phenomenologically. The most ignorant clod will start to see people with Down Syndrome completely differently after a few days working with them. Now consider this bit of rock awesomeness:
Zimmer is amazing in part because nobody has to spend time with him to see beyond his disabilities. It's just impossible to ignore his beauty when he's playing drums.
