I don't personally find Chaz Bono appealing, but not for any other reason than he just doesn't interest me. I don't care about his transformation from a woman to a man at all. His personality just doesn't do it for me.

I would be willing to be that the same parents griping about him being on the show let their kids play video games that are inappropriate or wear inappropriate clothes or watch too much tv in the first place. If you don't want to answer questions about his sexuality, don't let them watch the show. It's really as simple as that.
