HEY, YOU CAN’T DO THAT! At least not if you are a moral relativist. Greg Koukl, writing at Salvo, lays out seven things folks who claim truth is all relative cannot do (and stay true to themselves). The first of the seven things is accuse other people of wrong-doing. Remind you of anybody?
UPDATE: See also Wintery Knight’s analysis of why moral relativists are fundamentally hobbled when asked to justify morality on their worldview. And while you’re out, you might even check out HillFaith and my quickie look at the fraud that is Critical Theory.
