Why do people hate Garret?
Sure he was in a wheelchair but that doesn't mean he was a problem to the team. He kicked ass and saved others multiple times.
I don't think the show was trying to be PC like some other people think, especially since the characters didn't really act that way. Kylie wasn't a typical goth chick for example.
People in the cartoon didn't had a problem with Garret being in a wheelchair, Garret himself didn't think that. Remember the episode with the wish granting ghost?
Garret's wish was to play in NBA, but in a wheelchair, he didn't thought he was less worthy just because he was in a wheelchair, he often made jokes about it too. The dude acted like he wasn't in a wheelchair
Seems like the only people who have a problem with him being in a wheelchair are people who post here, ironically.
