>>>He added that one can conclude that the “social environment is indeed (homosexuality’s) main trigger.” <<<
I’ve known a lot of gays in my travels - I was once in community theater, and met a lot of gay men and women. Just listening was enough to convince me that homosexual behavior is a matter of culture and environment, not genetics. That’s not a very politically correct observation, but it is confirmed over and over - and now by this researcher.
It’s also seemed as if most of the gays I talked with started off with what might best be described as a seduction experience with an older gay person.
Again, that’s just experiential evidence, but it is compelling.
There’s also one other observation. I lived among Eskimos (Yup’ik people, to be precise). I’ve known literally hundreds of Yup’iks, and in small villages, where the sexuality of others is common fodder for gossip. I have never met a gay Yup’ik. You’d think that there should be some gay Yup’iks, if the so-called expert figures about 1 percent or 2 percent or 10 percent or whatever proportion of the population is “naturally” gay. I have never met any gay Yup’iks. On the other hand, I’ve met literally dozens of gay Americans of various ethnicities.
My wife, who was born and raised in Africa, also reports that she never ran into gays - until she became friends with South Africans of English heritage.
I vote for environment and culture.
Jung, as I recall, thought of widespread as the result of a confusion of sexual roles in urban environments. It seems to have been a feature of upper class society in England, where boys were sent off to boarding school at an early age.
