I don’t buy this. Homosexualists have always been with us, for whatever reasons. Some of the reasons are probably complex beyond our current ability to understand; other reasons seem to have been understood somewhat by honest psychologists in past times.
In the past we didn’t hear so much about or from them, because they had little mainstream support; and they are still a very small minority, regardless of all the women who have used hormonal ‘birth control’ over the past few decades, and even despite the recent ‘popularization’ of homosexuality..
(Even before oral contraceptives became common, there was a nutritionist named Adele Davis, who believed that additions of hormones to livestock feed may have been leading to ‘feminization’ of boys; but again, we have always had homosexualists, regardless of what ‘science’ has introduced to our bloodstreams/diets.)
It isn’t about an existing level of homosexual orientation, it is about an drastic increase over and above that background level.
Did Alfred Kinsey have anything to do with this change?
If the hypothesis is true, it merely means that the rise in homosexuality has an extrinsic cause - not intrinsic, meaning there is probably a treatment or cure.
It takes courage in this environment to come out with this kind of info. The social engineers understandably want to suppress such findings.
