Better question: If one gay in a marriage decides to go straight, does it invalidate their marriage?
My younger brother said he became gay because he “couldn’t get women”. That contradicts the idea that you are “born that way”, at least for some of them.
My personal belief is that as my brother became more liberal, he subconsciously realized that he was the oppressor class in all these liberal social arguments because he was white, male and Christian. It’s no fun being a liberal if everyone else gets to play the victim card, and you can’t. So, combine this with his social failures and he became a perfect target for recruitment in the gay cult. He finds acceptance and sexual gratification plus he now gets to see himself as an oppressed victim, not a hated oppressor.
But you’ll never convince me he was “born gay”. He chose becoming gay out of political opportunism.
Your younger brother is a quiter. He never figured out why god made darkness and beer?
It’s always a choice to commit the act, regardless of how the attraction came. One can have attractions, but one has a choice about how to act on them, or how to interpret them.
But that’s a good point, how do gays tell that anyone of them is truly gay?
Fact is, they can’t. Anne Heche, a singer, was supposedly lesbian, but after her “divorce” to Ellen Degeneres, she has been messing around in “Britney Spears” type marriages to men ever since. A number of other lesbian entertainers have done a similar thing.
