It was once a common belief that the world was flat and the sun revolved around the earth.
Further study proved that knowledge wrong.
What I am trying to say is that when and if homosexuality is genetically identified, the behavior will be bred out of the human species.
I wouldn't be too sure about that. In the first place, as a Christian who reads and believes in the Bible as the Word of God, I can find nothing scripturally to support that God creates a person to be a slave to what HE calls a sin. I don't pretend to understand the whys and wherefores of much that God does or allows, but I do know that He does not allow a temptation without a means of escape because He says so and He cannot lie.
"There hath no temptation taken you but such as is common to man: but God [is] faithful, who will not suffer you to be tempted above that ye are able; but will with the temptation also make a way to escape, that ye may be able to bear [it]. (1 Corin. 10:13)
It isn't like a child born with a disease or deformity. These things may, in fact, have a genetic component, but are in no way condemned as sinful. A person may even be born with a genetic predisposition to alcoholism because of the way in which his body processes alcohol. Is the predisposition a sin? Of course not, but being a drunk is, and an alcoholic is no more excused of his behavior because of that predisposition than anybody else who who drinks to excess.
In the second place, just suppose that science "proved" the existence of a gene that predisposes toward homosexuality. Given today's political climate, do you really think for a minute that the queers would sit still for future queers being eliminated? That would be predicated on the fundamental assumption that homosexuality is abnormal, which is exactly the opposite of what they're putting all this energy into making you believe. No, I think it would give them political carte blanche to actually "select" FOR it, breeding little genetic mutants in petri dishes to be implanted in host mothers. It has fallen to us at this point in time to change the direction this ship is heading and if we fail to do so, I truly fear for the world our progeny will inherit.
Take genetics out of the equation, and the "behavior" of homosexuality will still be around.
Today, gay is not only no longer considered taboo, it in fact has gained social acceptance as merely just another "sexually experiental option" -- thanks to American Psychiatric Association, the state-sanctioned sex-ed and moral relativism agendae promoted so heavily by the gay-infested National Education Association, and of course the Howard Sterns of the "entertainment" world.
