Wow. Parents have no idea what's going on in these alleged institutions of higher education.
Clear back in the mid 60s, my first college course in world history was taught by a black prof. He credited West Africans with discovering Meso-America, and carrying on reguar trade, centuries before Columbus. Egyptians were black. Most of the North African & all the Moorish Muslims in Spain were black; they were the ones the Europeans stole their knowlege and learning from, rather than the Arab muslims. On & on.
It reminded me of what the Soviet Union was doing in the way of claiming radio (Popov) airplanes, televison, and everything else they could as Russian inventions.
Any attempt to refute the BS just meant one was brainwashed, racist, or just plain ignorant.
At least my intro to astrononmy prof KNEW Ptolomaic astronomy was BS, but taught it anyway for the first half of the semester, to form a basis of showing what Copernicus, Keppler and the others had to overcome in divising the modern system, and HOW it was worked out.
