I find some of the questions here on R&S to be more interesting, and we actually see a diversity of opinion and even some interaction. Politics tends to be just ranters preaching to their choirs.
Anyone who thinks R&S is rude and impolite should visit Politics and you'll come back here with a better sense of appreciation, even for the 'other' side (if you perceive one).
I think R&S, despite its ideologues, generally attracts people with an actual interest in what others think (even if only to tell them thry are 'wrong,' whether they are or not), rather than the Politics people who just want to hear themselves rant.
