With news that even yoga classes are being cancelled due to fears of Westerners appropriating from other cultures, I am led to wonder -- why don't these prohibitions go both ways? If as a white western male, I can't do yoga or host a Cinco de Mayo party or play the blues on the guitar, why does everyone else get to feed greedily from the trough of western culture? If I can't wear a sombrero, why do other cultures get to wear Lakers jerseys, use calculus, or even have polio vaccines? Heck, all this angst tends to occur at Universities, which are a quintessentially western cultural invention. Isn't the very act of attending Harvard a cultural appropriation for non-Westerners?

I say this all tongue in cheek just to demonstrate how stupid this whole thing is. Some of the greatest advances, both of science and culture, have occurred when cultures cross-pollinate. I have read several auto-biographies of musicians and artists and they all boil down to "I was exposed to this art/music from a different culture and it sent me off in a new direction." The British rock and roll invasion resulted from American black blues music being dropped into England, mutating for a few years, and coming back as the Beatles and the Rolling Stones.

Or here is an even better example: the movie"A fistful of Dollars". That was an American western with what has become a quintessentially American actor, Clint Eastwood. However, it was originally an Italian movie by Italian director Sergio Leone (it was not released in the US until 3 years after its Italian release). But Sergio Leone borrowed wholesale for this movie from famed Japanese director Akiro Kurosawa's Yojimbo. But Kurosawa himself often borrowed from American sources, fusing it with Japanese culture and history to produce many of his famous movies. While there is some debate on this, Yojimbo appears to be based on Dashiell Hammett's Red Harvest, a classic of American noir fiction.
