I think this is evidence of the very sad epidemic of poor self-esteem and body image in our culture. People tend to think of it in terms of women, anorexia, plastic surgery and so on, but they often overlook the pressure on men. It's more insidious and subtle. But I know many guys who are insecure about their size or other aspects of their bodies.

I wonder if these are the same people who'd likely be conned into joining a dangerous or doomsday cult.
