Well, he would know.
Gay is made, not born.
Children are born a “blank slate” in regards to ATTITUDES about sexuality. The early experiences that touch upon this wellspring of of physiological urgings is what forms life-long attachments.
If a child of one gender gets the notion that children of the other gender are getting a “better deal” emotionally, that is the set of attitudes they will gravitate to. Reinforced about notions of passive or aggressive natures, these attitudes, which may be only fleeting, are either allowed to dissipate, or are hardened into resolve.
Counterpressures everywhere may shift the resolve one way or the other, but at the heart of the matter, which attitude will either appease or actively p*ss off the authority figures in your life? Which course does the child find the most satisfying? At some conscious or unconscious level, the person’s mind is largely made up, and with a clear conscience, so to speak, the person may then continue making the choices that feed that internal picture of self.
But it was always a choice, and not compelled by biology.
Continuing to make poor choices in life, over and over, in the face of all logic or a history of bad outcomes, is evidence of a poorly organized mind, or some would say, insanity.
Studies on identical twins show that if one twin is gay there’s only a 40% chance the other will be gay. Since there are known differences between men’s brains who are gay and men’s brains who are it’s likely that an infections disease is responsible for it(DNA can be ruled out). And it wouldn’t shock me to learn that that it’s transmitted through gay sex or random infection.
Quite a few of them deal with it by shunning alcohol all together.
