Being a racist isn’t being the devil.
Have you got a word we can use for racists who are the devil? You don't own the word. Some of us want being a "racist" to be evil. We need a word for those who do not believe in legal or social equality.
If "race" isn't a thing, how is anyone "racist"? But if race is enough of a thing to permit us to call an attitude "racism," why can't you find a word for the merely racially biased and let the rest of us use "racist" for the racist assholes among us?
