Just look down the front page as it is now if you can and you'll see a whole variety of different
debates. Most of them aren't politics, some might be related but the most part you can see the
diversity of debates.
Stick around a while, you'll see a big share of religious bunk, product preference polls, and pure
childishness. And if the site was mainly about politics you'd see most of the participants bored
and gone and then replaced by more serious contenders.
