Jared Wilson (remember him?) tries a bit of “marriage debate jujitsu” by turning a pro-equality meme against itself:
(via Stuff Christian Culture Likes, alias “the cesspool”.)
I don’t think it works. For starters, arguing that banning one type of marriage and allowing another type of marriage are equivalent is just counter-intuitive.
It also forces you to argue that marriage was inaccurately defined in America from the founding until Loving vs. Virginia. So Jared is arguing for marriage just as it’s always been … since 1967. You also have to explain how our founders – I’m sure they’re good and Godly men in Jared’s mind – could have gotten it so wrong with all their arguments against racial mixing.
