Since the modern concept of personal liberty and western "freedom" are uniquely the invention of the english-speaking white people (the Magna Carta, etc.), does that make a claim upon such liberties by anyone else a racist cultural appropriation? 

Such was the first question to spring to my mind after I read that white people enjoying pumpkin spice lattes was the same sort of thought-crime, because (of course) pumpkins and spices are historically the cultural assets of People of Color™.

I suppose we are all now possessively clawing the cultural accomplishments of our ancestors back into the closed domains of our little tribes. I'm just trying to see the endgame here.
