Your friends wouldn't be considered black.
I know a black tennis player. Before he graduated from his high school with a GPA over 4.0, he was a monster athlete, constantly training, doing cross country in the fall, soccer in the winter, and tennis in the spring, all of which he did varsity during his his last three years of school. At the moment, he's going to Berkeley, majoring in computer science.
I'm not hating, but I don't consider you or your friends to be black. Just from the way you write, my first impression of you is that of some urban, inner-city, ghetto gang banging trash.
Prove me wrong.
