You are either choosing to ignore or just willfully refusing to acknowledge that the cultures are not equal in racial standing or bias
I'm willfully refusing to acknowledge that this is a good enough reason to repeatedly take from Culture A while declaring that Culture B is off limits and thinking "All of your stuff is mine and all of my stuff is mine but you better not touch any of my stuff, you racist" is a good way to help bridge racial divides. What is this, musical reparations?
Of course, if we've reached the point where I should care about Whitey McJezebelBlogger's opinion on the holy sanctity of "Cop Killer" and whether it's properly reflected in some garage band's cover, I suppose that's making progress on the important issues. I don't know if any actual black musical artists give a rat's ass the same way she does.
