Cultural appropriation is everywhere. If these critics could take off their rose coloured shades and examine the details of life around them, they'd faint at the ubiquity of cultural appropriation. Of course, with their shades on, they only see instances of cultural appropriation with a handle big enough to drag around and harass. 

Asian restaurant owners profiting from running French cuisine restaurants. Not appropriation. 

Chinese and Korean owners of Sushi joints (Japanese culture) in Vancouver (most sushi joints in Vancouver are owned by people of Japanese decent). Not appropriation.

Lady Gaga features burqas in a music video. Not appropriation because it's perceived to be empowering burqa wearing women.

White guy writes about aboriginal culture? Somehow that's considered cultural appropriation. Because white men are not allowed to do so.
