During the years when Steiner was best known as a literary critic, he published a series of articles attacking various manifestations of antisemitism and criticizing some of the most prominent anti-Semites of the time as “barbaric” and “enemies of culture”.[329][330] In contrast, however, Steiner also promoted full assimilation of the Jewish people into the nations in which they lived, suggesting that Jewish cultural and social life had lost its contemporary relevance[331] and “that Judaism still exists is an error of history”.

This bit feels very reminiscent of the “kill the Indian to save the man” type of racism that led to residential schools. Sure, he may not have thought there was an immutable negative quality associated with race, but he seems to have been a cultural supremacist.

Given that we now know that race isn’t real, I struggle to see the actual difference.
