The author accuses liberals of blaming people who are fat on their diets.

You, on the other hand, blame liberals for removing some mysterious rules that govern greed and gluttony.

What were those rules, by the way?

I say, educating people on how to shop for locally-grown food (and eating it in moderation), rather than contributing to mass-produced food-like substances does, in fact, contribute to a healthier world and healthier people on it. You'd have a really difficult time convincing me otherwise. If the author is correct in stating that, "How fat you are has a lot more to do with your genes than with your behavior.", than Americans would be on par with the world averages, since we're a pretty homogenous society, DNA-wise.

We're not.
