I agree with you too, but don't think holding politicians to their lies or fixating on class warfare is really the most pressing part of the situation. He's calling for lynchings because he knows there's a receptive audience for it.
That's the part you should be most worried about, because a mob so empowered could just as easily turn its gaze to you. Good luck trying to be a nuisance to that prominent person once the mob gets a taste for blood. Before participating in doxxing frenzies or lynch mobs, nobody ever stops and thinks "what if this guy didn't actually do it?"
No expansion of the carceral state required, we'll just deputize an angry mob to play the part of Executioner.
