Dems and lefties always like to skip a step whenever they can.
In this case, like so many, the step they're skipping, is substantiating their allegations white supremacy, just like they do with the race card.
If they were forced, they'd have to admit that what they call white supremacy is nothing of the sort, by any reasonably accurate definition.
They just don't want conservative people or others that disagree with them standing up and calling BS on obvious BS, and so they drag out the boogeymen, hoping to silence about half of a nation by misrepresentation.
