This has been suggested quite often. I'm surprised moot didn't add it along with /pol/ or even /lit/. It would probably be shit though. Nothing but American history vs. European history threads and arguments about religion.

If we could make religion vs atheism, Holocaust denial, and race threads strictly /pol/, a /sci/ spinoff for Humanities & Social Sciences would be nice. That would include history, as well as philosophy and art if they don't fit /lit/.
But there isn't an urgent need for new boards right now.

/int/ could fall under that a bit, as could /pol/.
But like the other guy said, a Humanities and Social Sciences board would be good.
