I don’t think choice describes it. I believe “conditioning” is a better word.
The way I see it, someone may be a homosexual (through conditioning, if you will) but if they stay a homosexual, it is only because they CHOOSE not to be cured. Cures are not new — many people have talked about their own cure and their successful transition to a normal life as a heterosexual. But many homosexuals don’t want to hear it. They resist the concept. They CHOOSE not to seek a cure. Perhaps they became homosexual because they were molested as children. They don’t have spend their lives that way. But they choose to stay that way.
