What happen to our dance culture?

I swear americanized African American’s are a lost tribe of people, I get so frustrated and jealous being around my friends of other cultures and ethnicities, because they are so in tuned with their culture and heritage right down to the music and dancing. For some reason we African Americans, the majority of us at least, could care less.  You throw on old school reggae, soca, meringue, bachata, and people will rush the floor. You dare throw on Al Green at  party and the floor will clear, suddenly its time to go to the bathroom, visit the bar, complain about the DJ, or its a sign that the party is over, unless by some miracle there's an abundance of older people at the party, or its a theme party. What do we know about old school music other than the few Frankie Beverly and Maze tracks, a few MJ and Jackson 5 tracks and the electric slide. Even then, we don’t know how to dance to the music,  and for god sake hope we don’t have to ask a woman to dance,what was the last dance we had, lean with it rock with it, super man, snapping, what was the last real dance, the cha cha slide? The only dance we pass down now is the electric slide. The art of slow dancing has been lost on popping, grinding and bouncing, standing still and letting a girl gyrate on you. When a slow song come on the only people dancing are couples or drunk people.  When we get older, late twenties and beyond we still only know how to dance like we at spring break freshman year of college, cant step, do the mash potato, the hustle nothing. We can pretend like we can break dance, don’t act like you’ve never seen two cats in the club doing a horrible job pop locking with a crowd around them, making every breaker in america sick. We don't even know hip hop. I mean we know nothing about dance, nothing that involves actual technique or footwork or anything.  Are we trying to break the typecast that we have  rhythm by not dancing or something, IJS dancing is a part of culture and we've lost ours. Its a shame, how can we be so proud to be so uncultured, when sitting on a goldmine of culture and history, especially when we have some of the worlds best music and artist, revered all around the world but we aren't proud of it. WTH? We got to do better.
