While I don't consider myself an advocate for same-sex marriage, I reason thusly:
1. A marriage is a civil contract between adults.
2. Adults have an untrammeled right to engage in any contracts they like, so long as those contracts do not infringe the rights of others.
3. A marriage contract infringes no one's rights who is not a party to the contract.
4. It is therefore the business only of the parties to the contract whether they contract, and of what that contract shall consist (subject to the caveat in #2 above).
Note that I didn't say anything about "two adults" in there. If three or more adults wish to engage in a marriage contract, that's fine with me.
