Apolitical synonym for "racism" [duplicate]

For Y and y, you may use the words racialism and racialist.

"Racialism" is an emphasis on race or racial considerations, as in determining policy or interpreting events. It is the belief that human species are naturally divided into distinct biological categories called "races."

In this Huffington Post article titled "Racism and Racialism Are Different", it is written that:

Racialism is rational, morally neutral, and inevitable in a society with our history of slavery, discrimination, and white-black social differences in so many areas.

The proper way to refer to "the belief that there are innate and meaningful differences between races" is "abyssal ignorance." In particular, ignorance of the current state of our knowledge of human population genetics. "Race" is tricky to define, and if you use skin color, you end up with as large a genetic variation between races as within them. You'll have better luck defining race by ancestral geographical origin, but only for making valid statements about correlations within populations, not about individuals. And geographical origin isn't always a good fit for societal definition of race. Please forgive me for leaving to you the task of researching the term "human genetic diversity."

It was not always thus. The Ngram viewer will reveal that the terms "raciology" and "scientific racism" were in vogue in the 1920s, but events in Germany starting in 1933 put a dent in their popularity. Probably the high point of the scientific endorsement of racial principles came in 1962 with the publication of The Origin of Races by Carleton S Coon, a professor of anthropology at the University of Pennsylvania and Harvard University and one-time President of the American Association of Physical Anthropologists. With the advent of the civil rights movement shortly thereafter in the US, the coupling of political views to the term "racism" became permanent.
