It's basically about putting a low value on the life on non-white civilians.

So would you call the bombings of civilians during WWII "racist"?

I haven't argued that fact. I'm advocating for having a broad number of words which multidimensional meaning.

So you would agree that there are some statements that are both "racist" and true.

I see no reason to treat someone who makes wrong claims about race

What do you mean by "wrong"? If you mean "wrong" in the sense of "false", you've yet to present any evidence that any of Satoshi Kanazawa's claims are wrong.
