Miss Ann Thrope, you will be amaze at the level of understanding, scholarship and knowledge we humans have on each other. You should read some more and read books that make you uncomfortable because they challenged your comfort zone. You are talking about African slaves that came in several decades after the founding of Jamestown. What you appears to forget is that the first blacks that was brought ashore came from a captured Spanish slave ship. English had no real history of black slavery before this so they took them in as indentured servants like many of the whites who there as well. Most of the initial  indentured blacks were freed later on. They form the core of free black Americans until the ending of the Civil War in 1865. Do you not know your nation's history, Miss. Thrope? Of course, it is important to understand that without black slavers, there cannot be black slavery in the United States.. Are you that blind to the obvious? Black slavers enabled white racism!!! Ironic??
