Liberals define "racism" not as it logically is. Their definition is that "racism" means anything that upholds Western civilization. One liberal used this definition: "Racism is a structural oppression that benefits white people combining prejudice/discrimination with power"--meaning 1. it must be accompanied by the societal power to enforce it (thus, Blacks, etc., can't be "racist," since they don't have power--yes, I know); and 2. that anything that benefits Whites in any distinct way MUST be "racist." The reason is that to oppose White culture, etc., is to break down Western civilization (which is why liberals support Muslims and Muslim terror). So they develop this loaded term that makes it impossible for most Whites to respond.
Hence, "anti-racist" is indeed by liberals' own definition, "anti-White."
That's how PC works.
