You might feel very different if you were the parent and lived with this difficult situation your entire life.
Maybe. On the other hand, a girlfriend of mine who has a D.S. son is not offended, and neither is New Hampshire Duo, who posted, "As the parent of a special needs son I can’t say that I am really offended by Zero’s remark. However, it does show that he is elete beyond his abilities and just plain not up to the task at hand." As I posted, I work with Special Olympics kids, and it's true that many of them are nowhere near as adept and graceful as the ordinary athlete, but they make up for it with determination and guts.
The point is that Obama thinks he's better than the rest of us, and that being bad at bowling is a point of honor, something to brag about. In this remark he's not poking fun at himself, he's boasting about being a member of the elite who never go to bowling alleys. It's not about special needs kids, it's about how much better he is than the rest of us.
