I don't disagree with much / any of this, but I will just offer that the fat acceptance movement is the way it is because if you separate the "good fats" (i.e. the ones that workout a ton and eat "right" and are still fat) from the "bad fats" (i.e. the ones that behave in closer-to-stereotypical-fat ways) then it's just as bad as the rest of society etc. etc. etc.
I do agree with you, though, and I resent how much damn effort it has to take me to get a little exercise. I know fine well that I would certainly weigh 20-30 pounds less if I worked a physical job-- that's what I weighed while I was waitressing-- but I don't have time to get that much exercise in my life. (I was exercising probably 40 hours a week, because more than half my time at work was spent running around, plus I was doing roller derby which was insanely intensive. I got down as low as 175 before my muscles started bulking up and then I switched jobs and my body didn't know what to do.)

But yes-- the problem is systemic, not individual, but if you dare say that someone has any possible way to be thinner than they are, you're against the fat-acceptance people, etc. etc.

I wish I could make my point more clearly but as I just made clear in my previous post, I do not have all the lights on my string illuminated today, so I apologize and this is the best I can do.
