I agree that we should at least encourage monogamous and stable relationships among everyone, heterosexual and homosexual. Like it or not, there will always be gay people, and while you shouldn't be forced to accept or respect homosexuality, we should at least try to be respectful of people. To use an analogy: I hate black licorice. I resent the fact that because some 5-10% of the population likes black licorice, I have to hand-pick out licorice candies out of the box. But I'm not about to insist that black licorice be banned just because myself and the vast majority of people find it disgusting, and I'm not going to treat people like dirt if they do like it.
And to be perfectly frank and upfront, I've had numerous gay friends, all of them monogamous, and none with HIV or VD, as far as I know. My best friend throughout high school and college was FLAMINGLY gay-and more flaming and he would explode like a Spinal Tap drummer. But he was and still is even more conservative than I am (except on abortion). He's currently a pre-med student, and is always writing letters criticizing Canada's socialist health policy to newspapers. My MA advisor was a lesbian, and I remain in touch with both her and her partner. They're a truly lovely couple who have always accepted my politics, which are very different from theirs, and I've always been grateful for their enormous amount of help in getting me into a first-rate Ph.d program.
There's a lot of ignorance and phony science on these hate-the-home threads. After pointing out some of it, I realized I was talking to zealots. I would argue more and point out the crap, but zealots are not swayed by logic and talk of freedom and liberty. I will join in a fight to protect children, but those who foam at the mouth about adult rights and behavior can pound sand.
On my way to the airport. Best wishes.
