Since I attend an HBCU, this is not a personal issue for me. However, I care about what is going on with my sorors around the world, so I feel compelled to respond.
Soror, I agree with the others who encouraged a service-related group effort. This actually goes beyond the Greek aspect of society. We need to start letting the other people of the world know that being Black is not all about running faster, jumping higher, and getting our party on. I volunteered in a classrooom once, and I was appalled at what the teacher said to some of the students. I was there during their career fair. The teacher was pushing Black children towards entertainment and sports, while promoting business to the white students. It was in response to a question that a child (Black girl) asked. She wanted to know how to "get rich." The teacher told her that she had a beautiful voice, so maybe she could be a singer. (True, the child can sing.) This didn't seem so bad until they all started asking how each of them could "get rich." I started to notice the pattern when she told a white boy that being CEO of a company paid a lot of money. I was so angry. Mind you, this class was the gifted and talented class. Why was business or the sciences not pushed to all of the kids? I said something to her a few days later. Of course she conveniently forgot about what she said to each individual.
But my point is that we are so much more than the life of the party or merely the entertainment. We have made major contributions to society as a whole that should not go unrecognized. When they insist on us buck dancing and providing the entertainment, we should steer them towards more worthwhile activities. Yes, a public service project probably would have gone a lot further than teaching them to stroll. But I admire your willingness to foster harmony between the groups.
