Kirkland: Do you know the difference between something being of choice and being social? I could never choose to eat a dog. NEVER. but its still social.
That's nonsense. You could eat a dog. If you were starving, you could eat a dog. You would, in the end. And you would be choosing to do so. I could never find a woman sexually attractive. Never. Not for a microsecond. No matter how hard I wanted to.
It's not a set of boxes, it's a spectrum. People vary from totally homosexual to mostly homosexual to bisexual to mostly heterosexual to totally heterosexual, with incalculable shades of variance between each of those goalposts. But they do not move along that spectrum. Just like the color spectrum, light at a blue wavelength can never be red.
Because if sexuality were changeable, then it'd only be a matter of time before the gay-hating straight supremecists try to find ways to chemically or psychologically force everyone to be straight, just like their Demon God demands.
Because I am gay. They only claim to not be gay because that's what some monster in a pulpit told them they had to be in order for God to love them, and because they have no sense of self-worth they go along with it, back into the closet Hell on Earth to escape the 'real' thing later on. Or they were bisexual all along, and were thus never gay in the first place.
But given the hatred and rage most of these "ex-Gays" have towards gays who continue to be honest, I'd say the former is far more likely than the latter.
