I keep wondering, how will gay polygamist marriage, civil unions, or even just mere tolerance of homosexuality polygamy, stop heterosexual people from finding each other, and producing offspring?
Do you accept your line of reasoning when it comes to other forms of marriage?
The US policy on marriage can be one of two things: 1) all marriage between consenting participants must be allowed; or 2) only marriage between a man and a woman shall be recognized by the state.
Show me any place in America besides the deserts of Utah and Nevada where women are willing to act as servile idiots for some lazy lump of a man who wants to see how many kids he can father, and I'll agree that polygamy as an "other form of marriage" is a potential problem. Even the "free love" communes of the sixties did not inject polygamy into our society. Liberals don't even practice it, unless you count getting divorced and remarried repeatedly.

What about this for a concept: You only have one of yourself to give to another. You are allowed to give that one indivisible self to another who can freely consent to give their one indivisible self to you. There's your logical, practical, and moral argument against polygamy, bestiality, adult-child marriage, and marrying an inanimate object (shoes were mentioned earlier).
