One of the great achievements of the long civil rights movement was establishing a broad consensus that racism is evil. Trumpism is trying to roll back that social-accord — and as we saw in Charlottesville and on January 6th they have had some success in doing so. But for now, the majority of Americans still find explicit expressions of overt racism repugnant. Which is why today’s white-supremacists assure their followers that if some law, action, or statement does not use a racial slur or make explicit mention of race it cannot be considered racist.
