Are fat people (generally) to blame for being fat?

[HagridOfTheDeep]

I believe people need to take responsibility for themselves. But I also believe some people are more susceptible to becoming overweight than others.

It always irritates me when thin people, who've never been overweight in their lives, suggest people who are overweight are irresponsible or disgusting because of what they've done to themselves. It may be their own fault that they're like that, but these thin people have no idea what it's like. They have no idea how challenging it is or what it's like to feel so dejected.

I think one of the things that actually bothers me the most in his world is when "fit people" tell "fat" people to "get themselves in shape" like it's just some switch they can flick on. As if to say "it's easy for me, so it should be easy for you, you gross pig."
