Self-pity? That is laughable. I could care less what the majority of the western world thinks about the ex-gay movement, just as I cared less about the majority opinion during my active gay life, which started in the 1960's.
As to modern research, what research and what studies? Le Vay's esoteric theories about brain similarities between gay men and women have been disputed by his peers; Hamer’s research has also been shown to be false by his peers so you don’t have any real empirical research on which to base your statement. You can appeal to anecdotal studies but name one empirical study that establishes homosexuality is genetic, innate, or unchangeable behavior. All of your professional organizations taught and practiced shock therapy, chemical therapy, aversion therapy, and other barbarous treatments in an attempt to “cure” something that cannot be cured. Behavior is a choice and why one practices a behavior can have a psychological basis. Treat the reasons and you can change the behavior.
