Hey troll, guess what. EVERY UNMARRIED ADULT IN AMERICA (who is not incarcerated or been barred by court order) is eligible to get married.
There is not a single law in any state that prohibits homosexuals from getting married and there never has been. Homosexuals have EXACTLY THE SAME RIGHTS when it comes to marriage that everyone else does.
Not a troll at all. The argument is that non-gays, not romantically involved, not wanting or able to marry, could form a sort of partnership. Elderly friends or siblings, for example.
In fact, maybe they can do that right now.
The original point, of course, was that this idea is not inherently anti-conservative.
