Here's something from Slate which I sincerely hope will not become a part of our national debate anytime soon:

Sodomy and adultery laws do seem outdated and silly. But if those laws are repealed on the grounds that consensual sex is private, it's hard to explain why the reform shouldn't extend to other laws. What about bigamy and incest? The "polyamory community," claiming support from the ACLU, accuses the military of persecuting polyamorous troops. A Web site dedicated to "Full Marriage Equality" calls on supporters of the DADT repeal toconsider

the men and women who risked their lives (and those who gave them) and endured so many things in service to their country, who haven't been free to be who they really are and share their lives openly with the person or persons they love. Shouldn't someone who risked their life for this county be able to marry someone of the same sex, or more than one person, or a biological relative? Or at least share a life with the person(s) he or she loves without a fear that their own government will be against them? Is bravery and valor negated if a man loves another man, or his long lost sister?

The problem with this, to say the least, is that though we have just removed the "Don't Ask, Don't Tell" ban from the rules which govern our military, it will probably still require another generation for homosexuality to become truly accepted in our society. Furthermore, the arguments alluded to above which relate to a "right" to marry one's biological relations or to marry more than one person are some of those that are used to argue against gay marriage, which will in all likelihood be the next barrier we need to remove in the cultural wars over homosexuality, and this nonsense cannot help but complicate that set of goals.
