White supremacists are the newest mass hysteria, like Nazis were in 2017.

We'll have 6 months of fevered panic with media declaring them hiding behind every bush until a new crisis overtakes the conversation.

The problem of course being, as illustrated by the responses, is that the hysteria cannot distinguish between the active threat and the ideological bias.

Don Lemon calls all Trump voters KKK members.
Ben Shapiro is a dangerous extremist.
All right leaning media must be banned.

The left is incapable of discussing the fringe, largely underground movement of actual extremists that the actually dangerous individuals attach themselves to.

They choose to accuse all on the right of being secret Nazis or white supremacists.

That is the mass hysteria.
