What I find fascinating about this poll is that the percentage of gays in this country is so small, yet if you were to watch network television or the news, you’d assume half the population was homo.
"Genetic predispositions"? We're still at the "maybe, maybe not" stage on whether that even exists. It's especially dicey when the "definition" of gay is itself cultural. Many languages don't even have a word for it; in contrast, there are cultures which assume that a predisposition to sodomy, as to drunkenness or gluttony, is more or less universal, and goes by the name of "concupisence."
"Puritans, Mongols and Muslims"? Show me the survey of gay Puritans, correlated with the lab results for the sequence of the gay Puritan genetic marker. Published by a reputable Plymouth Bay Colony journal prior to 1690.
Puh-leeeez.
