I recall some things Thomas Jefferson wrote concerning the intelligence of Blacks. I do not recall everything exactly except it agreed completely with what modern IQ tests show.
I do recall that Math and abstract reasoning were their weak points but he considered them close to equal to whites in verbal skills.
One historical dead give-away is to consider if several hundred thousand Caucasians were held in slavery, it would not take 150 years for the rest of Caucasians to rescue them or at least try. Did any Africans even attempt to rescue their kin? No, they tried selling us and the muslims more.
I feel sorry for those held in slavery, whether it was as agricultural workers and servants or as pawns for liberals.
What we are experiencing now from the out of control African-American culture is plain and simple Karma Police for our ancestor’s selfish and cruel stupidity. If they over power and prevail, as they certainly wish, we will all end up no different from any African country.
"Biased testing." "Differences of IQ types that aren't measured on standard tests." "Do not 'test well' for many various & sundry reasons." Other Lib excuses.
Consider, however, HOW their ancestors were 'selected' for shipment: it was NOT for intelligence.
OTOH, people like to toss out the high performance of Asian students, and call it "cultural".
Again, consider that the Asian population, to a much greater extent, has SELF SELECTED for immigration for reasons of IMPROVING their lot; and to flee from persecution of intelligence and education. Naturally, cultural norms of valuing hard work and study apply to the Asian students, just as the opposite applies to a huge proportion of the black "students"; but the base mental material is very different.
Clearly, that proves conclusively the Thomas Jefferson was racist. The entire Congressional Black Caucus already knew that, since they were toddlers...
