1. People like to argue its not a psychological choice, without any evidence for what it really is. It just "must be" genetic. We'll find it someday. Maybe we'll find the Arab polygamy gene too; and then we can explain why the Chinese had polygamy for 5000 years until Mao made them stop. He "must have" had a mutation ray gun.
2. As some pagan explained to me why he didn't support gay marriage, its not religion its engineering. Its like demanding you build something with two lug nuts or two carriage bolts instead of a lug nut and a carriage bolt.
3. Careful, you're treading on the genetic theory of homosexuality.
4. Indeed.
5. Marriage is going to wildly change? Will American polygamy come back?
6. Very true. It was the popular legislature that created the Convention that established the Bill of Rights; it was the popular legislature that set up the Bill of Rights and the 13th, 14th, 15th, 19th and 24th Amendments. The People, after all, are supposed to be the fount of law, not technicians with the title Judge. BTW what "right" are we talking about, the "right" to have everybody in America abandon their views and take on yours?
7. Organized religion is well protected in America; its the private conscience that's under vicious assault. E.g., 'i don't support gay marriage because -I- think its a sin'.
8. But what if I could say I was tall, and telling me I was short and mistaken was a hate crime?
9. The territory of Utah had legal polygamy; Congress made them ban it to become a state in 1870. "Crazy" is a hate word.
10. Indeed.
11. So the greatest democracy on earth should be rewritten by diktat?
12. How about bisexuals? why should marriage be limited to two? Can't we have a line marriage like in "The Moon is a Harsh Mistress", where the marriage is a corporation? If you say no, aren't you being discriminatory based on your own prejudices?
The core joke of Hitchhiker's Guide to the Galaxy is that of course no civilization would develop personal computers with instant remote database recovery, and then waste this technology to find good drinks.
Steve Jobs has ruined this joke.
