Well Bob has his theory and I have mine.
Those pictures are only going to appeal to gays. They aren't bodybuilding photos at all. They are pure fagbait. Muscle soldier, muscle lumberjack, muscleman on the cross with skimpy underwear.. then, when anyone points out how blatantly homoerotic these pics are, you resort to 'you must be gay to see them as gay' ..what next? a pic of you and TP French kissing 'you must be gay to see that as gay'.
I don't think Chick is gay but I think he feels saddened and a bit ashamed that he has to resort to doing gay softcore to make a living and is very defensive about it.
