All I meant was that there are a LOT of factors that go into being fat. Absolutely, eating too much and not exercising enough is a big factor. But my point is that 1. You can't tell by looking at a person why they are fat and 2. Even if they could be skinny by choosing to work really hard to lose weight, it's ok for them to choose not to, to have other priorities.
I mean, everyone could get a PhD if they tried hard enough, right? Just study hard, be willing to take on debt and go to school for that long... What's that you say, some people just don't have academic aptitude? So they should just try even harder! Get tutoring, have to study 3 hours for every 1 hour their classmates have to study. Otherwise, they're just being lazy.
