From time to time moral crusaders of all colours, from the loony Left to the religious Right, and not forgetting modern radical feminists, stir up moral panics around the issue of human sexual behaviour. Claims that pornography objectifies women, that our children are being sexualised or that thousands of women in prostitution are forced to work against their will are carefully analysed by Dr Magnanti and found to be untrue. Don't be put off by Dr Magnanti's past (she worked as a call girl under the pseudonym "Belle de Jour"). She is a well-educated, qualified scientist and an accomplished author. I like the calm, scientifically objective approach she has taken in dismantling nine modern myths about sex and sexuality. Even readers who are not particularly bothered either way about subjects such as pornography, prostitution, sex addiction and the like, may find the book interesting because of Dr Magnanti's descriptions of the shocking extent to which moral crusaders will go to twist the evidence, make up data, ignore the truth and lie to the public in order to gain political influence.
