I think slavery should not be taught to the extent that it is in schools. It's over and long gone. No need for negative modern day individuals to focus soley on it while hating and accusing white/black individuals. We should know that slavery once existed but not exploit it in classrooms.
"Freedom is never more than one generation away from extinction. We didnít pass it on to our children in the bloodstream. It must be fought for, protected, and handed on for them to do the same, or one day we will spend our sunset years telling our children and our children's children what it was once like in the United States where men were free.
