"All black athletes want to be rappers and all rappers want to be athletes." "All female sports are inferior to men's sports." These are just two of the many statements you have probably said to a friend, heard around the water cooler, or simply thought about while checking out YouTube freestyles and WNBA highlights on SportsCenter. Hey, it's cool. We've all been guilty of it at one point or another. And, as the Bible states, "let he who is without sin cast the first stone." Yeah...that's what we thought.
