You're taking very specific examples of people with legitimate disabilities, which always exist and need to be accommodated, and using it to bash the idea that maybe, just maybe, there's a large percentage of the population who are, in fact, responsible for their own issues. I'm sorry, but we have a major obesity crisis in this country. And it's not just that if affects people's appearances or keeps them from riding the latest Disney ride. It is killing people. And the vast majority (not all) of the responsibility is on the individuals themselves. It's time we stopped being afraid to say that. We're not doing anyone any favors by pretending otherwise. And the presence of people with legitimate disabilities does not change that.
