I'm sympathetic insofar as I think the 'cultural appropriation' critique has often gone too far.

But what needs to be known is that African-American artists have created incredible, magical intellectual property -- only to have it monetized by white people, while the black artist gets nothing. That's simply wrong. And that's where the focus of cultural appropriation critiques should be, not a "you can't touch this" approach to any sort of engagement or homage to other cultures.
