I don't think obese is attractive either, but then, I don't think tattoos are attractive. But we aren't judging people with tattoos. We are judging fat people. It is curious to me that in discussing obesity there is rarely- very rarely- any compassion for the fat person. Drug addicts and alcoholics are expensive too, but they aren't judged. They have a "disease".
Before you ask, no. I am not obese. And no, I would not be as fit and trim as I am without working at it. Most of all though, I see no reason whatsoever to wag my finger at someone else for not looking the way I do.
