Could it be that widespread mental illness might be part of what causes them to behave the way they do in their sexual proclivities in the first place?
Not a PC idea, but one that has not been debunked! When the Psychiatrics removed Homosexuality from being listed as a mental illness is had absolutely nothing to do with any new research proving that it wasn't. Simply Politics.
Actually, the entire question sent the APA into a tizzy of trying to define just what a mental illness was in the first place and whether or not there is any such thing - which goes to show how totally worthless the APA is.
One sign of a mental illness is an inability to accept reality. If I were to declare myself Napoleon, and to insist that France accept me as their Emperor, that wold be a sign of mental illness since I am not the Emperor of France. (It would also be a sign of mental illness because who would want to be? But I digress.)
Everyone is born in a heterosexual body. That's reality. The claim to be homosexual is an inability to accept reality. That's a mental illness. Fortunately it can be treated. Just as I no longer demand that France enthrone me, former homosexuals live happy heterosexual lives.
Of course, I won't deny that I miss the lavish parties they used to throw for me at the palace, but really, I'm doing quite well now, thank you.
Shalom.
