"Cultural appropriation" is usually understood as a one-way street: A privileged outsider steals from a disenfranchised group and eats the profits. This is an easy enough narrative, but the truth is generally more complicated—see Little Richard's gratitude for Elvis Presley as an "integrator." Or take James Franco and Travis Mathew's new film Interior. Leather Bar, a fascinating instance of cultural "appropriation" that feels like cultural exchange.
