re: #6 Sergey Romanov

Sure they do, the point is that it is perfectly legitimate to make an assertion that cultures are unequal, while the opposite is possible in principle, but a mighty weird position.

Yeah, I guess the only way one could make “all cultures are equal” work is if one were talking about the subjective feeling that (I believe) most people have about their culture (or country, state, city, sports team, religion, etc.) being “the best” or at least “superior to x”. Gawd, we human beings are a contentious lot.
