there are those who did not ‘dream up’ what you state as ‘born that way’. they have concluded ‘born that way’ from their biblical research / study. that is what the post is all about.
I read an interview by Anton LeVeys son. He stated that he did not believe “born gay” and that it was thought up based on the civil rights movement. He said a “gay gene” will never be found. But he’s still pushing gay rights.
