When I read the script [of Glee], the whole premise was that all the high school kids were being cruel to this kid in the wheelchair, and then the quarterback comes along and has a heart of gold and takes him out of a Porta Potty. That's too often what I see in media, that the characters with disabilities are there to make other people seem like heroes for treating the character with a disability with respect. Those are the kinds of roles that are out there.
