Today’s False Charges of Racism Echo Soviet Communists

When and how did it become acceptable to make a false accusation that someone is racist?
For adherents of religions that revere the Ten Commandments, with their injunction not to bear false witness against one's neighbor, such accusations are divinely prohibited. For those who find moral instruction elsewhere, the problems with such false accusations are readily accessible to reason. False accusations of racism erode respect for truth and for the gravity of the charge. They risk boomeranging. They injure innocent people and make it harder to fight genuine racists like the ones in Charlottesville.
