This is ridiculous!
Homosexuality is a behavior - there is no biological basis for homosexual behavior.
You are 100% correct and that fact has been lost sight of by the intentional obscuring of the issue by that for a number of reasons. One is their running from that word and adopting the term"Gay" in it's place. Just look how many people use that term even on this sight. They've brainwashed the public.
I for one refuse to use the term "Gay" to define their perverted conduct. It's intentional conduct that had at common law been illegal and also statutorily in most states. To here them say it's in their genes and can't help it is the same as an Arsonist saying he can't help starting fires and shouldn't be held accountable.
America better wake up and smell the coffee before it's to late, if it isn't already!
