Plenty of "left-wing" political ideology is just as anti-materialist as "right-wing" political ideology, especially when both are concerned about laws, liberal rights, the legitimacy of moral principles, etc. Communist politics are the only politics that are possible for a genuine materialist. It we take the materialist position as the default one, it follows that the board should be named /politics/. In his Politics, Aristotle's name for the best of all possible constitutions is simply "Polity", because for him the constitutions of all other polities are perverted in some way. In the same sense, communist politics are the only Politics and we should not hesitate to make that clear.
