What pisses me off is if a white man/woman did this then people would just brush it off. From the controversy stemming from Gabby Douglas's hair and now to Serena's dance it's like white people are looking for any little thing to downplay any success or achievement by black people. Seems like perfect examples of implicit racism.
That's just the system doing this, the average white person won't know what she's doing and probably try the dance themselves.
This isn't new. What the media, who need some type of controversy, does is find some black person who will complain about anything that makes black "look bad" or just gossiping some negative shyt and the media blows it up like it's serious and actually accomplish their goals. They're shills. Back in the day things like this wouldn't get blown up so bad but because people gossip on social networks they can find anything to report about and make it look more serious then it is. They reported on the gabby hair thing from post on twitter which could have been started by someone they are associated with and people ran with it, albeit not that much. Look at the movie "The Corporation" to see how news outlets really operate and who has power over what they report.
What people don't realize is police and media are always looking at social sites and forums to see what people are taking about and use it to watch certain people and make a case against them or make a story to report.
