I find acknowledgement of one's disability often disarms and diffuses a lot of situations and comfortableness. I had a teacher in high school with Tourette syndrome and on Day 1 of class he explained what it is and what it causes him to do. Instead of pretending it wasn't happening he disarmed it with knowledge and openness. People shouldn't have to do this and they don't have to but it helps. It's almost as if people don't accept it as a legitimate problem (whatever it is) until they know the cause. My ex-gf's mom has muscular dystophy and she was overweight from steroid treatments and wheelchair bound. But she could still move her arms and legs so when we'd go out she just looks like a fat lady that's too lazy to walk or something. It wasn't obvious what was wrong because all of her limbs moved. I'm sure people saw her and thought "Well, typical overweight American. Look how they let themselves go. Ugh." But it was beyond her control and a legitimate medical condition.
