Query: Read his books about herbal medicine

His real name is Michael A. Weiner. Before he 'became' a radio talk show host he wrote herbal medicine books and was a darling of the San Fransico left wing crowd. His claim to fame was swiming naked with left wing poet Alan Ginsburg in Fiji. I am not certain this guy is serious - my fear is he is putting on an act to make the 'right' look like a bunch of crazies. I've listened to his show and read his book, and I don't know if he is being serious. If you look at his past, you would might agree.
