With the repeal of "Don't Ask, Don't Tell", Vice President Biden and gay activists are spinning it to suggest gay "marriage" is inevitable. I wouldn't be so quick to draw that conclusion.
The precedential removal of three Iowa Supreme Court justices for judicially imposing gay "marriage" on Iowans, efforts in other state's to repeal gay "marriage" laws and the potential for passing state marriage amendments in other states would suggest momentum is in other direction.
Frankly, the more the issue is debated and discussed the better. People will realize the nature and purpose of marriage. It's more than a "loving relationship" between two people. Instead it's profoundly connected to procreation, the raising of children, and the unique, complementary relationship of a man and a woman.
