Agree'd. "Racism" is part of the PC Narrative.Actually, "racism" has been a rather new concept in human history. Prior to the African slave trade, slaves were merely of the poor of any color. People looked down upon each other in accordance to tribal identity or class. In the beginning of the Atlantic Slave Trade, Africans were merely a good source for cheap labor to supply the demands of early capitalism. The African slave trade saw blacks to Europe, the Middle East, Asia, and South & North America. The American South became dependent upon the plantations and they became a very lucrative business for the U.S. because cotton materials were exported internationaly. Slaves were treated far more humanely in states like Louisiana where the Catholic church in Fance prescribed conditions. Protestant States like Kentucky were prescribed absolute freedom to treat slaves as they wished by the Protestant church in England.
After a while it became natural in all slave owning states to associate slavery to blacks. But in the Protestant states slaves were viewed as less than animals in dire need of care taking because they were viewed as having the inability to educate and maintain morality. Some, like George Fitzhugh (Google him), even advocated a sense of socialism towards society where all poor people (blacks and whites) should be slaves. The argument was that poor people hadn't the means to feed themselves, but blacks slaves were free from the burden of having to find work and were cared for by the master. This view spread amongst plantation societies (with the poor white part dismissed) because it "legitimized" slavery as a moral responsibility. In time, "race" became the deciding factor for inferiority and the concept of "racism" unfortunatley became a concept far more predominate in the U.S. than the other locations.
Racist thoughts and impulses may be human nature, but "racism," as we know it, was learned.
