The Reverend Lewis Farrakhan got a grip on this phenomenon many years ago. When he was excoriated by jews for criticizing their BELIEFS, and they called him "Anti-Semitic," he observed that while anti-Semite "used to refer to someone who hates jews, now it refers to someone whom jews hate."
And so it is with "racist." Racist used to mean someone who hates Blacks; now it means anyone whom Blacks (and their white toadies) hate.
Exhibit A being Our Beloved President, who has never uttered a racist word as President and has never taken a racist action, and yet the "fact" that he is a racist is presumed in our compromised Media.
