Whither Wozniacki (a mini-treatise)

Predictably, tennis player Caroline Wozniacki's 'impersonation' of Serena Williams continues to stir controversy. I gestured yesterday at the thought that this is a tempest in a teapot, but didn't develop the thought. Since people keep finding new ways to insist that this is yet another example of anti-black racism (and other bad things), I should think about this some more. Especially since my intuitions pull me in the other direction.

I've followed this thinking wherever it has led me, which I'm sorry to say is into prose very much like what one would find in an academic journal article. So I'll apologize for that in advance, and make a concession that I learned from watching '300': this will not be quick, and (I fear) you will not enjoy it. (Also, there will be no pictures.)
