Twerking = Cultural Appropriation?

Has this word/phrase become as annoying to you as it has to me? “Twerking” Every time I hear the word I cringe. Why have we made this “act” so popular? Is Miley Cyrus to blame? Or is she just someone to exploit the obscene gestures we as black women have been doing all along?
There was a recent article in the New York Times written by Teddy Wayne titled “Explaining Twerking to Your Parents”. He states: “Explain that twerking is a dance move typically associated with lower-income African-American women that involves the rapid gyration of the hips in a fashion that prominently exhibits the elasticity of the gluteal musculature.”
After reading this line multiple times I had to take a step back to recognize what he sees and why he feels this way. Did I become offended, yes at first, but then I realized that there’s some truth in his statement. If you think about it, who do we see doing these moves? Just type in YouTube, “Twerking” and you’ll be astonished at the results. It’s just sad. We as African American women have to do better. But now that Miley Cyrus is exploiting the act, we as “WOMEN” need to do better. Then Mr. Wayne went on to say, “They will reasonably wonder why Miley Cyrus, who is white and wealthy, does it at every opportunity. Patiently respond that, Ms. Cyrus, twerking is a brazenly cynical act of cultural appropriation being passed off as rebellious reclamation of her sexuality after a childhood in the Disneyfied spotlight…”
Hilarious, Mr. Wayne. Really “cultural appropriation”? The definition of cultural appropriation is “the adoption of some specific elements of one culture by a different cultural group.” So is he right? Is “twerking” an element of African-American culture?

This whole thing annoys me and makes me feel that the entire world needs The Black Female Development Circle, Inc to come to the rescue of all women. We all need to self-develop, stay educated, explore, enhance and celebrate womanhood.
Please read his entire article. I would love to hear your opinion.
