Well, the people wearing "6MWE" and other anti-semitic tshirts certainly were.

We were discussing the infiltration of white supremacists in law enforcement. Not sure what your question is getting at in regard to that discussion.

I'm sure if you went and asked them if they were racist, most of them would not claim to be. But, considering that the stated purpose of the protest is founded on the continued belief that the only possible explanation for Trump's election loss was a epic-scale government conspiracy, we're not exactly dealing with a group of people whose beliefs about the state of things are easy to reconcile with reality.

Speaking on a more macro scale, the movement that produced that protest and this insurrection is so transparently rooted in racism, with roots going back at least as far as the Southern Strategy, that we're now to the point that trying to apologize for them is, at the absolute best, an act of petty denialism.
