Well, HN is meant for quality discussions of things we find interesting. Sometimes politics is relevant to us (or at least to enough of us to qualify).

The trick is to keep it a quality discussion, rather than letting it degenerate into a flame war. That's not easy. But if it can't happen here, where can it? (And if the answer is "nowhere", well, I'm not sure that the answer is wrong, but that's one of the most cynical statements possible about the current state of politics.)
