CATHY YOUNG: To the new culture cops, everything is appropriation: Their protests ignore history, chill artistic expression and hurt diversity.

A few months ago, I read “The Orphan’s Tales” by Catherynne Valente. The fantasy novel draws on myths and folklore from many cultures, including, to my delight, fairy tales from my Russian childhood. Curious about the author, I looked her up online and was startled to find several social-media discussions bashing her for “cultural appropriation.”

There was a post sneering at “how she totally gets a pass to write about Slavic cultures because her husband is Russian,” with a response noting that her spouse isn’t even a proper Russian, because he has lived in the United States since age 10. In another thread, Valente was denounced for her Japanese-style LiveJournal username, yuki-onna, adopted while she lived in Japan as a military wife. In response to such criticism, a browbeaten Valente eventually dropped the “problematic” moniker.

Welcome to the new war on cultural appropriation. At one time, such critiques were leveled against truly offensive art — work that trafficked in demeaning caricatures, such as blackface, 19th-century minstrel shows or ethnological expositions, which literally put indigenous people on display, often in cages. But these accusations have become a common attack against any artist or artwork that incorporates ideas from another culture, no matter how thoughtfully or positively. A work can reinvent the material or even serve as a tribute, but no matter. If artists dabble outside their own cultural experiences, they’ve committed a creative sin.

Hint: The more people talk about “cultural appropriation,” they less they’ve contributed to a culture worth appropriating.
