I've been reading a few things about the appropriation of elements of other cultures by the dominant ones - usually white American culture - and how it can result in "exoticization" of such non-dominant cultures or use of their symbols without respect or knowledge towards them. For instance, the use of Native American warbonnets/headdresses by white people (outside of the proper ceremonial occasions), as well as dressing up as an "Indian" for Halloween* can be quite offensive to those cultures.
With that in mind, I do wonder... Considering the way cultures interact, is appropriation part of the whole "coexisting cultures" deal? What is or isn't appropriative? Are "Chinese" restaurants with food adapted for non-Chinese tastes offensive/imperialistic? Where do we draw the line?
