I would say that western rape culture is just one small part of a larger, world rape culture. The rape culture may differ between countries and regions, based customs, traditions, and heritage, but they're all predicated on rape. I mean, does it really make a difference if England prefers doggy style, and japan prefers missionary? Not at all, because you're ignoring the thing that matters, the rape itself. It all goes back to when out ancestors were monkeys, raping each other in trees and bushes. Rape is literally ingrained in our species DNA due to evolution, as a way to continue the species. It formed over millions of years. Getting rid of it will take more then a few years. In this regard, I think it's important to criticize rape culture wherever it may occur.
