Total opinion, but an opinion based on life experience and an extensive look at the history of humans. I could be wrong, but I don't think so. There has been homosexuality in every culture since day one...homosexuality was openly practiced in Rome, Greece, China, Africa, and among the indigenous peoples of the America's(ancient world). China even had a term for it..something of the flower, can't remember right now. The ancient philosophers wrote about it in not unflattering terms.
With the advent of organized religion in later years, it has been systematically vilified.
