So does it mean that it is not genetic?
I'm told that only half of all homosexuals are gay from birth. The other half get sucked into it later in life.
"So does it mean that it is not genetic?"
They have searched for a genetic link for years with little success (although you wouldn't know it if you listen to the MSM or the many ignorant layman activists). Since they had no luck with their attempts at finding a genetic cause, they are now looking to biological developmental causes.
These people have a serious problem with wishful thinking, they assumed people were "born that way" long before they even bothored to conduct research. Because of this, expect them to try something else when their little "womb theory" doesn't pan out.
