Query: very sensible - on the surface

Mr Edell is a strange individual. He sounds intelligent, humerous, and sensible...unless you actually pay attention to what he is writing or saying! Then it becomes manifest that this individual is not quite sane. Why are most Blacks incarcerated? Because of "police racism", says "Doctor" Edell. Normal men are secretly "turned on" by watching homosexual men says Dr E. A mixture of good advice and madness. Do yourself a favor and save your money. There are a lot of better books to buy!
