Parents making their kids fat is abuse.
It's a choice for a person to be fat. And parental guidance that might act like that is a form of abuse. It's like you're forcing someone to become someone he doesn't want to.
I don't think parents really want to make their kids fat because that's could be called abuse. The problem is that parents are also fat and they think there would be no problem is their children will be the same. They don't think it's a problem for them.
