jackie,
There are many folks with disabilities who lead productive and fulfilling lives, not "in spite of their disability", but because they are motivated, skilled, determined individuals. The disability is a neutral in their lives. That's a great attitude on their part and a great lesson to us all. But we have to be careful not to fall into the "super crip" way of thinking. Such folks aren't noble because of what they are able to achieve. Rather, they are more like every other student than they are different.
