For the third time, I am not taking it personally -- I am asking you to say WHY you think such an odd disparity should be the case.
If you haven't understood what I'm asking this time -- well let's give it up.
But let me try to give you a tiny hint, and another try:
Students, please write an essay on why, in a nation with a large majority of white people, in which, at one time, a large majority of the black people within it were slaves, and why their respective populations are inversely represented in the prison system.
Don't want to do it? Then don't -- I can't fail you. But I can understand you better.
