(Just in case you're serious.) Even if homosexuality is purely genetic, it is at least a recessive trait so even a gay man and a lesbian having a child togther does not guarantee a homosexual child. So, in that sense, they can't reproduce, even though they can have a child.
What I realized a while ago is that theists encouraging homosexuals to suppress their desires and live as heterosexuals only increases the potential for gay children. Considering how recessive the genes are (or dependent upon environmental factors), the increase is not going to be much over the short term but if the suppression continued over centuries we could see a shift in the percentages.
I seriously doubt that the pastor in question meant that homosexuals can't produce homosexual children - actually, I'm pretty certain he meant that they can't have children at all
. This is an argument I've heard way too many times to misunderstand it. The last one took a form of (I'm paraphrasing here): "If a gay guy has sex with a woman in order to have a child, he's not really gay." Errr. Yeah. Sure. So if I have sex with a man I'm not at all attracted to I'm really attracted to him. Or something.
Considering all the evidence currently available, it seems to me that homosexuality is the end result of a variety of (unpredictable) genetic, biological and environmental factors. Suppression and 'healing' of homosexuality don't work and they only produce a mass of unbelievably unhappy people. It's unproductive and harmful.
While we're at it I must add that I find it rather interesting that the loudest opposition of homosexuality these days comes from the home of the free, a country that supposedly cherishes individuality above all. I'm not American, so my judgement might not be accurate, but I can see right-wingers aggressively defend their right to do as they please (even if it is harmful to others), and denying that same right to everyone else. Well, it's the same in my own country, so I do have quite a good idea what it looks and feels like.
This only works if the fence really does keep the kooks out. (And homosexuals are people too so it wouldn't exactly be a utopia. But I think it would be better.) What worries many people is that the Nazis started the same way - rounding up the gays and gypsies while spreading propaganda about the Jews for 5 years. Would guys like him really care about Jews? I doubt it (although it's possible). But once you have the general population used to you rounding up undesirables, people will accept it when you start including other groups.
My idea was meant a s sort of a joke. I guess I didn't formulate it as well as I wanted to.
But I fully agree with you. It is a bit of a slippery slope argument, but it's perfectly valid as far as I'm concerned. The simple truth is that people like that pastor in the original post function on discrimination. I doubt that homosexuals are the only people he has a problem with. Actually, I'm fairly certain that the only people he wouldn't fence up somewhere are those who agree with him. Kooks, that is.
