You should care, because Exodus International is the spokesgroup above all others for your side of the religious aisle when it comes to this issue. If the very ex-gay organization above all others that speaks for all others doesn't say homosexuality is a choice, then that should be a signal to you that you are yourself wrong about it. You should care, because these are people to whom Christians (and with you, believe me, I'm using that term very, very loosely) tell people like me to go to. If you don't believe them, then why should anybody else?
You see, these people, even though many find them disagreeable, do, at heart believe the Gospel and there is no way on God's green Earth you can impugn their morality or their theology without falling into the trap of exposing yourself for the bigot, the moralist, and the Gospel-denier you are. Further, somehow I don't think you have it in you to share the Gospel with a gay person. You'd rather spout off about how immoral they are without any refernence to the Gospel. Like so many fundamentalists, you are all Law, no Gospel, more comfortable with pointing out others sins than anything else. You see, the Gospel is that Christ alone is the perfect substitute for the sinner, not Christ, a membership in a Restorationist church, and getting them thar sins washed away when baptized by an approved Administrator, and hopin you don't mess up and loose your grace before you die. That's not faith in Christ alone; that's not the Gospel. But that's what your group teaches, and you've given more than enough evidence by the way you act and the things you say that you don't believe the true Gospel - you're just cultist who uses his cult to validate his bigotry, racism, and misogyny. Of course, I also don't think you'd know the Gospel if Jesus or Paul walked up to you and preached it to you; after all, you deny Romans, James, and Galatians abd the best you can muster when contradicted by somebody who actually knows these Scriptures is "show me your credentials" (which, of course ultimately undermines you ability to explicate the Bible yourself, as I've pointed out already, and to which you didn't respond, which I've noticed is your habit when you know I've cooked your goose well in front of eveybody - best give it a few pages and ignore it or change the topic, beat a hasty retreat to save face and hope nobody will notice).
And I think, at heart, the real reason that you don't like homosexuality has nothing to do with what the text of the Bible says, rather, like so many others, when the real KT shows himself, it amounts to "Gays - eww," because, deep down, you know that the truth of the matter is that the only way you can justify discrimination against gays in employment is to call them "immoral" based on what you think they do in bed, not what you can prove they are doing - which at heart exposes your own sexual immorality, for it necessarily requires that you are far more obsessed with gay sex that any gay man or lesbian is. You are, at heart, quite the voyeur.
And I am sorry for you, so very sorry, but there is no chance of you becoming President or the EEOC passing into obscurity any time soon. So, you're going to have to do better than "Gays -eww" to justify discriminating against them in employment. That's the real world in which we live, not your 1950's throwback fantasy world or the world of moral hypotheticals that have no present application.
