What I was saying was that one shouldn't discount the fact that most fat people ARE fat because they eat too much simply because there are also a number of fat people who are fat for different reasons beyond their control. Yes, of course one shouldn't tease people about their weight, but in situation where it's made obvious that someone IS fat because they're a greedy pig (as is frequently the case with fictional overweight villains), I don't think there's anything wrong with condemning them for their gluttony, on top of any other flaws they may have.
