The problem with the whole Casey Martin situation isn't that he's using a cart, it's that the government is stepping in and forcing the PGA to change their rule in his case just so he can play. If the PGA themselves decided to let him use one then fine, it's their rules, they can change them if they want. But the government doesn't have the right to, and Casey Martin does not meet the requirements of the PGA tournament. It sucks for him, yes, and I'm not just being sarcastic, it does suck that he has that disease and can't play PGA golf because of it. But this isn't about emotion, and lots of things in life suck, it's not the government's place to step in and "fix" them. I'm not going to be all insane and predict that this ruling will set the stage for America to turn communist like some people have, but it could very well lead to more instances of the government overstepping it's bounds and violating the rights of people and organizations. And that is what really sucks.
