That is correct, but that's because it should be that way. It's more insulting to Serena's career than an illustration of hypocrisy to imply that those two be covered in a similar light. To be clear, they weren't implying it was a race issue. Instead, they thought that a positive drug test would have resulted in reactions of "well THAT'S why she's so muscular" or "THAT'S why she's been so dominant", etc.
