I'm empathetic towards most things, but I can't stand fat people complaining about being fat. I view being fat as a lack of self control. You need to be able to manage your impulses, if not then you should at least take responsibility for them. Instead of looking for excuses.
That obese American actor, I think she was in Precious, goes on all the time about being happy with herself and her weight. That's perfectly fine, for her. If she's happy, then good. She shouldn't be shown as an example of self-acceptance though. Being that way isn't good, most people couldn't do that mentally.
Being obese isn't fine. It's a physiological and mental red flag.
(I'm on about being obese, not just overweight)
