Didn’t Darwin originally say that black people were basically sub-human? Evolution is racist. Many of the “primitive” features of skulls are found in modern black/African skulls. Lower forehead, smaller chin, etc. Whenever a textbook shows a “primitive” skull and a “modern” skull it is always showing a white person’s skull for the “modern” one. It’s obvious to anyone who’s studied forensic anthropology.
You’re not compliant in applying the term “racist” in the approved, amorphous political sense, and that is where your confusion arises.
