Saw that myself while in college. I had many good friends from Lebanon and I picked up more than a few of their common swears and insults. One very common insult was to state that you had intercourse with the person you were insulting. I never understood this and questioned them about it. They insisted that only being on the receiving end of such behavior made one gay. They could not get it around their head that any sexual contact with someone of the same gender qualified both men as gay.
In certain Afghan tribes when warriors go off for weeks / months at a time a man will take a submissive male with him to sodomize while away from his wife. The wife certainly isn't going off to battle with the men and taking a submissive male on the trip is perfectly normal to them.
The idea that people are born gay is preposterious. How would any one explain people who were once gay but whom are no longer gay? Equating being born gay to someone born black is laughable but heard from any number of people. What black man wakes up one day and decides he is now Asian or white?
Anyone claiming people are born with a same sex attraction must logically extend this claim to people being born with attraction to children, or animals.
Some men are wild for slender women, some to voluptuous ladies and some white men claim they are only attracted to Asian women. Are these men all born this way? Of course not. It all based on prior and early experiences in that man's life.
The original premise of civil rights in the 60's was how could you discriminate against someone based on something they could do nothing about, like their race or gender?
The radical homosexuals picked up on that and have been pushing "born gay" ever since as a way to nullify anti-homosexual laws.
But it's a scam, as you make clear. Only if we accept the premise does their claim hold water...and it's a false premise.
