Everyone in the pro-marriage racket has been promoting Mark Regnerus' fine piece in the Washington Post, "Say Yes. What Are You Waiting For?" I agree entirely. I see my students putting off the thought of marriage right after college because they think they should get all their ducks in a row first. And they have lots of ducks.
The best line from Regnerus:
"Marriage actually works best as a formative institution, not an institution you enter once you think you're fully formed."
