No. Because not all fat people are gluttons.
I went from 130 to 195 lbs in my mid 40's eating virtually the same amount of food. It was disgusting, but it was due to metabolism not gluttony.
I've had to increase exercise and eat less to get back down to 150 lbs.
So I don't agree that all fat people are gluttons.
By definition all fat people are over-cosuming gluttons, but, despite the time spent on it, this is not my main point.
My point has more to do with the mote in the other fellow's eyes and the beams in our own. Homosexuals are not the only persistant and unrepentent sinners among us under the laws of Christianity nor even the most common. Anger, envy, sloth and all the rest are all too common and it is, I believe, a defensive reaction to focus on the homosexual while ignoring the sins a whole lot closer to home. Perhaps even as close as our own bellies.
