I went through a brief slatebro contrarian phase. Not sure how bad I was but I can’t deny the possibility that “Will Saletan has a good point!” was something I said once.
What’s the dumbest Slate-syle/very serious sort of thing you ever believed or argued in favor of? Mine is a two-way tie between telling my dad that they should “teach the controversy” on evolution (which I took directly from a Gregg Easterbrook article) and saying (to whom I forget) that maybe Fareed Zakaria was right that by invading Iraq and improving relations with Iran we could establish a bloc of US allies in the Middle East. (Note: I was against the war by the time it was being seriously considered.)
