I guess what I'm saying is that culture is a commodity, that we live in a time when exchange of culture is quicker and easier than any other time, and I don't see why people are so het up about it. They hang it all off this entitlement / appropriation framework which seems exactly the same as the idea of privilege; casting people in minority cultures as victims who can't draw from more 'powerful' cultures.

Seems like nonsense; Australia and the US are not monocultural, there's definitely some cultures that are more successfu within the societies; personally I find it logical to talk about successful cultures because some of them will be more successful. A culture as a collection of mores and strategies for its own propagation is in competition.

Apparently that point of view is invalid just because I'm from a winning culture, but there's nothing stopping someone from a less successful culture labelling mine; I just probably won't care. But why would they care what I think of their culture either?
