The new credo:

(1) Racists were maybe not the nicest of White people, but racism ended a long time ago. All White people today are nice (non-racist).

(2) People who today call nice (White) people "racists" are not nice people. Because of this name-calling, they are violating the principle of niceness.

(3) In fact, people who call White people racists today are themselves racists, even though racism ended a long time ago.
