I was going to come in here and pee all over your fun, but it seems Shiny has done it first. Oh well.
With the ever-expanding influence of gimmicky dance moves, actual hiphop artists have began speaking out against them.
These are actual rappers speaking out against the commercialization of the genre. This type of music and dance were meant to be empowering, and now it's becoming a disgrace to African Americans. They use blackface, a practice that dehumanized African Americans for decades, to illustrate their point. But instead of white people dehumanizing them, these are black people doing it to themselves for money. And do also note that Harlem, the place of the Harlem Renaissance in which African Americans contributed and created music, literature, and culture has nothing to do with the Harlem Shake. All in all, it's disgraceful.
And I don't mean to deny you your fun. I just ask you to look at the implications.
tl;dr Harlem Shake is stupid and rude.
