Fat acceptance is an anti discrimination movement aimed at creating laws that punish people for discriminating against the overweight, I am completely against this.
Being fat is not a problem unless you see it as a problem. In the roman days, being fat was an attractive thing, showing wealth. As times change, so do our preferences in other women, or men. And that's what it all boils down to. They're just people, with different body sizes.
They don't deserve to be taken the piss out of just as other religions don't, ginger people don't, and other nationalities don't. But they will be. All of them. It's the way we are.
Just because we tale the piss out of people, and they take the piss out of us, doesn't mean we hate each other, and by saying this, it sounds very much like you hate fat people. I'm sure you're not perfect.
