I was greatly disappointed by this book. It's not a scientific, scholary or in any sense academic work. The author rarely cites the source for any of the studies which supposedly support his ideas. Certainly not in a way that would enable anyone to further investigate them. The book seems to consist of gross generalisations and statistics that are plucked out of thin air. To some extent I started of accepting that it was a certain type of book, lightweight and not to be taken too seriously, but after a while, even accepting this, you eventually get tired of reading 'facts' like 9% of men in big cities are gay, but only between 3 to 4% in the suburbs and only 1% in the countryside, 1% of women are lesbians, 30% of peadophiles are attracted to their own sex, 30% of lesbians don't want children, gay men are x times more likely to have a first degree than straight men, y times more likely to have a Masters and x times more likely to hold a PhD. I just found myself wanting to scream "How can you know that?" all the time.
