This is one of the things where the nature of the modern United States makes it hard. I routinely go around telling people that the current regime in Washington is illegitimate, nobody should obey them or listen to their lies, and that I look forward to the day they're ripped from their thrones and tossed in prison. In most places and times saying that would make me a revolutionary, but in the US it's not even arguably a crime.
What counts as doing stuff? Minneapolis has been hitting the streets for days trying to chase a major federal agency out of Minnesota, a cause which I and my elected representatives publicly support. But it's a huge country, Minneapolis is thousands of miles away from me, and outside of airport security I haven't personally seen an agent of the federal government in years. To me, following federal agents around blowing whistles at them and yelling that they'd better leave town seems at least a little revolutionary - the feds certainly think so, they murdered someone for doing it this morning. But it’s also unambiguously permitted under US law.
