Morris does seem squeamish about Gay Hist-orgy, but this is a review -- not a news article.
The long debate over Gay Marriage has had the tendency to alter our perception of Gay Life. One cannot argue that "we are just like you" to Heteros, while explaining the great benefit to society for Gays' having tons and tons of temporary sexual partners. Tricks is a better word. Although we can never go back to prove or disprove it, 9/11 might have been averted if even one or two of the field operatives, who were trying to alert the bigwigs to the Arabs learning to take off but not land, had been Gay. Chances are reasonably good that the field operatives would have tricked with a few of some FBI bigwigs and they could have called on the private cell phones and made certain this vital information was not ignored.
Organizations with lots of Gays develop alternative routes of communication. Gay life is less stratified and a Gay doctor is very likely to be friendly with a Gay plumber, etc. Sexual attraction cuts across all other lines separating men, especially when it is only for a brief trick. (Yes, it is often about "new."). Gays have relationships across a great age range. Although Gays tend to be aggressive, they seldom allow that to turn into violent aggression. That's why there are so few fights at Gay bars.
So for now, it is sooo Politically Correct to deny that Gays are any different from Straights, but statistically we do have different socialization patterns, and those patterns are good for us and for society in general.
