It's just a secular leftist response to Conservapedia that mostly focuses on debunking (mostly far-right) pseudoscience and conspiracy theories. I think you're taking the name a bit too literally and the concept a bit too seriously.
Conservapedia and Wikipedia don't call themselves "rational" and the other guy took it seriously, not me. I know its just a bunch of whiny losers. What if conservapedia called itself the unbiased wiki and everyone quoted it?
