You know, it is.

Plenty of racists historically wanted to "uplift" the savages, mostly through cultural assimilation, but occasionally through interbreeding. Neither of these could fully uplift them to our level, of course, but at least they would be better off than they would be on their own. "developing a political and cultural framework for something like "compassionate eugenics" (using as little coercion and stirring up as little drama as viable)" has also been a fairly obvious position for, y'know, actual racists, as opposed to the stereotyped klan member people are thinking of when they use that signal.
