Just from looking at strangers, you'll notice that fat people tend to be more frustrated-looking than those of normal size. It makes sense — you're ugly because you failed to stay in shape, and your weight literally makes it a chore to even move. All that messes up with your brain chemistry and you start to feel like a loser, so it's probably all too easy for these people to feel like the whole world hates them and that they should hate it right back.
