I totally agree. The email I sent to the article writer included:
"Your logic is completely flawed. You stated, 'I just don't understand. Children with disabilities are allowed to take the same classes in school. They aren't forced to learn in separate environment.' Those with the same mental capacity are in the same classes. Those that have a lesser mental capacity are in something I'm sure you remember well, special ed. Different activities for people with different abilities."
It seems to me that the girl going around the track in a "race" that counts for nothing, will just result in a lot of pity from the onlookers. The situation focusses attention on the wheelchair and not on the kid. A lot of people seem to think things along the lines of, "oh its so nice they let that little cripple kid join in the activities". That does little to promote a positive image of those with disability.
I'd much rather see the girl compete in the para-olympics. There she would just be a jock and the fact that she is in a wheelchair means nothing.
