yeah we may argue vaccines, circumcision, abortion, food stamps, and may other stuff, but nothing brings the claws out like a math problem does. It makes for quite humorous comments too, including, but not limited to, "The answer is this, duh!" "no you're wrong, it's this!" "you guys are such idiots, the answer is this!"

By the way, for those who know what post I'm talking about, the answer is 14 :)
