Reading Taylor's piece made me want to come up with a good counterexample to her argument (the argument that the WWE sometimes neglects to push wrestlers based solely on their ethnicity). Two wrestlers came to mind: Dolph Ziggler and Kofi Kingston. Neither Dolph (a Caucasian male) nor Kofi (an African American male) are World Champs, nor will they likely ever be, despite their talent as wrestlers (though Ziggler has held the Championship twice: once for 11 minutes, 23 seconds in 2011 on a technicality, and once for 69 days in 2013 as a result of a Money in the Bank cash in). They are the kind of guys that can do well in a low card or a high card match. They can be used in any feud and they can pull it off well. They won't be put in the title position because their characters can be utilized in so many other ways, like by helping others make their way to the top. While putting people over might not be as fun or glamorous as being the Top Dog of the business, Dolph and Kofi (and Sheamus, for that matter) are great at it, which keeps them away from having a consistent top card spot.
To credit Taylor's case, I can't think of many popular and successful non-white wrestlers (with the notable exception being the Rock). That may be because non-white wrestlers with the WWE are stereotyped into ethnic categories (i.e., "being Asian is his gimmick,"), or it might just be based on a lack of talented non-white wrestlers in the WWE. The question, I suppose, is whether the WWE just chooses not to push non-white talent, can't find highly talented non-white individuals, or simply chooses not to hire potentially successful non-white wrestlers. If you can factually answer that question, you'll be able to truthfully say whether the WWE is or is not racist.
