People who call antiwhiteism "reverse racism" are falling for the false linguistic trick that racism is always something White people do to non-White people. The very term "racism" makes people think that a White person is discriminating against a non-White person, that's how deep the false narrative has sunk into people's minds. So call anti-White racism antiwhiteism, cuz that's what it is. And never call it “reverse racism.” That’s plain stupid!
And always capitalize the word White when talking about White people. It's a proper noun. Proper nouns are capitalized.
