Andy Dehnart of RealityBlurred returned to my America Weekend show today to talk about this summer’s reality TV shows. I asked him if CBS’ “Big Brother” was having the same problem as last year with contestants who spew racist and homophobic nonsense, and whether network head Les Moonves was aware of them (considering the host is his wife, Julie Chen). We also discussed the latest singing competition, ABC’s “Rising Star,” whether that whole genre has run its course, and whether Fox’s “American Idol” can pull out of its tailspin. And somehow we ended up talking about the trend of reality shows with naked contestants.

Listen to our conversation here.
