Suppose homosexuality can be prevented medically. Then it will tend to die out as most parents choose not to have homosexual kids.
Ah, you miss a point or two. First, what are the chances that enough of those supporting and willing to pay for parental genetic manipulation are those opposed to homosexuality? Strikes me that few fundi Xtians would be keen. Well, actually, I can't think of many parents who'd be happy to undergo massive modification of their sperm or eggs on the chance (since that's all it is) that any surviving seed might be both healthy and not homosexual... Would you volunteer? [I would not!] And, of course, I assume they're fine with throwing away all the embryos in which this doesn't work? Ooops, I forgot - this is now murder, as defined by Bush. So let's cut the numbers again.
Next, bear in mind it would take perhaps 15 years to determine, if the resultant embryo survived, so what then? It's a tad late to abort. And if you then discover it's both brain-damaged and gay... Hmm. Meanwhile, of course, one successful case of GM straight does not mean that all can be treated the same way.
And finally, of course, let's look at the Darwinian points to your argument: Suppose homosexuality can be prevented medically. Then it will tend to die out as most parents choose not to have homosexual kids.
Homosexuality has survived at least 3000 years, and probably though not provably is as old as humanity. This argues for some compelling genetic advantages, somewhere, or it would have been bred out. So, it's likely that any society culling these would be weakened, perhaps critically if reproduction is at such a low point that the minor numbers of homosexuals are significant compared to the breeding population... and die out.
But their predominantly gay children will not reproduce. Equally false, I fear. Nothing says that someone homosexual is unwilling to parent. Since we have already established reproduction independent of gender, those richest and most eager will reproduce. And by your argument, these 'liberals' so keen will breed gays equally eager to multiply, and they will do so with the power of science and planned parenthood at their command. Who knows, perhaps these teeming gay hordes may use the power of science to outbreed the refuseniks still clinging to Nature's ways... Of course, the vast majority will be lesbian since that's cheaper and easier. Darwin-style. |
