It was the Proud Boys! Dressed as Antifa!
Attaboy.
Ahead of the riot, Biggs told followers of his on the social media app Parler to dress in black to resemble the far-left antifa movement, according to the affidavit.
This Proud Boy organizer wanted his followers to look antifa-ish.
There's a lot of conspiracy theories and paranoia, especially on the Right.
If they are worried about antifa infiltration and
somehow deduced that antifa plants will turn around their MAGA caps to identify themselves to other leftist plants. It's only one more step for some MAGA folks who engage in violence to fake the alleged antifa tip-off, in order to be able to deflect blame later. (and of course some bro idiots genuinely turn around their hats when they want to show they are ready for action).
So things start getting weird.
There's already been one skinny black guy who was at some leftist protests this Summer, but the Left/antifa crowd at the time denounced him as a right-wing infiltrator. Trump supposedly blamed antifa for the Capitol attack. But what's pretty clear is almost everyone involved has been a die-hard Trump supporter with plenty of Proud Boys, 3%ers, Oath Keepers, QAnon dupes, along with other assorted racists and right-wingers.
