That's a figment of the media. The "far right" and the huge collection of "white supremacists" that have been drummed up as some huge evil plot in America has, as far as I can tell, zero basis in reality.

Note that basically everything done by white people is a "far right" "white supremacist" plot. E.g., AOC refers to the (hilarious) "insurrection" (the unarmed, leaderless one that waltzed into some of the most protected space on earth with nary a problem) as a "white supremacist" plot.

If you buy that, you're an instrument, played like a fiddle.
