Rod Dreher quotes a young adult who supports gay marriage:
Your conception of marriage, the traditional one, is that a man and a woman get married for the purpose of procreation. Marriage isn’t really about romantic love in this conception, but rather a framework for the rearing of children. If we take for granted that this is what marriage is, then I don’t think it’s bigoted at all to not have gay marriage, so long as the coupling is respected.
The problem for people my age is this: your definition of marriage was displaced prior to our lifetime. I have no memory of when that definition was true. Virtually everyone under the age of 30 has lived their entire lives under a culture that believes marriage is an expression of romantic love between two people.
