How do you square that with African Americans demanding to identify as such, Asian Americans demanding to identify as such, etc?"All white people are born racist"---come on. Then we're all born racist, every last one of us.
Racism is because of a category error. Racists believe that their own race usually is in a category of men all by itself, and everybody not in that fictional category isn't as equal as those in the category. But there is no category, so really the racists are seeing things. And you protect against hallucinating people the same way you protect against evil people, you defend God-given human rights to the death.
Are they hallucinating?
