It absolutely works, when you have control of the history books. It will be memory-holed, and the narrative will be that the damn dirty Chuds were defeated through heckin' valid diversity and Democracy

.
You hear all about MLK, the Freedom Riders, the OG Summer of Love, etc. Never about the Watts riots, the child prostitution bust that prompted the Stonewall riots, the 1968 DNC, the Days of Rage, or the Weather Underground bombings.
Liberals do not inform, persuade, or convince. They humiliate, ostracize, and silence. And like the Islamic doctrine of
taqiyya, their belief that they are on the Right Side of History

means they have no problem with lying to get their way.
