I've always viewed it this way: Africans were tribal groups, little to no advancements. Finally, the leftest, the global delete thought they found someone they might be better than and could control and teach to tie the deletes shoes. (metaphorically . . . or maybe for real!) But that view quickly melted away when Africans showed they could become a whole lot smarter, inventive and productive than the global leftest ever could be.
So they engaged in mental trickery to keep the African slaves down.

In my view, the global delete, the so called kings a queens were the dummies of the world and NEVER Achieved Conscious Introspection nor any meaningful integration of knowledge.

I'm sure there were exceptions but basically they were inbred retards.

Nicely written and thanks for posting. IMHO leftists don't "hate" blacks any more than I could hate a set of wrenches or a hammer in my toolbox. To the left, blacks are tools to aid in reaching a goal. Former president Lyndon Johnson is attributed to explaining it best after the passage of "The Great Society" bill: "This will have those n-words voting Democrat for the next 200 years". Any negative consequences experienced while achieving the goal are irrelevant.
