I’m much more sympathetic to jettisoning “racism” than I am to jettisoning “race.” Ethnicity is no more biblical than race is. Our vocabulary is not limited to words that occur in the Bible.
I’m sympathetic to the insistence that “mankind” is a single entity—a single race, if you will. But that’s just one of the meanings of the word. Plus, we don’t entirely deny the various ways that we’ve broken mankind up into groups based on various traits, especially as descendants of various men.
