Read up on the Moors and you will learn that it was the Moors were not only Black, but that they were Muslim. White people are deathly afraid of one thing; a Black Muslim. When the slaves were first brought to America they were forced to convert to convert to Christianity, because White people learned that many of them were Muslims; which White people should have known, because they were purchasing people that had been caught in warfare from the Kingdom of Mali.
The Moors built Colleges and Universities that thought accounting, business, law, engineering, astronomy, biology, chemistry, medicine, law, etc. They also taught how to build cities and proper sanitation.
