I'd love to hear an example of someone who got fat or stayed fat because of 'fat acceptance'. Americans didn't suddenly become fat because it became acceptable. It's becoming acceptable because so many Americans (with Europeans following suit, especially in the UK) are fat now that accepting it is realistic. The AMA mistakenly recommending everyone to limit their fat intake which resulted in starchy foods being considered 'heart healthy' and food companies marketing on that had a lot more to do with it, IMHO.
I'm not anti-Christian. I'm anti-stupid.
