If creating an "autonomous zone" in the middle of the United States isn't sedition, then I don't know what is. If you want to forgive it because it was a bunch of deluded incompetents, then you should probably forgive the Capitol seditionists for the same reason.

Well, in the middle of Seattle. It's not clear whether chaz intended to secede from the US or merely Seattle policing; their demands were certainly very local so I suspect they really had no intention of leaving the US itself.
