I would never advocate or incite for imminent lawless action. I would advocate for a change in public policy that included things currently held to be illegal.
As long as it makes a difference, the first amendment protects your right to advocate for changes to law and policy. You just can't tell people to right now go and break a specific law if you have reason to believe they might.

"People should shoot maga fascists dead in the street and hang them from lampposts" is protected because it's saying what society should do, not actively calling for people to go do this.

You got me, officer. I'm a coward who's all talk, I would never do anything I described.
