Provocative Messaging

I'd like advice, please.

Going to the protests tomorrow. First time protesting. And I really want to wear/bring provocative messaging to voice the intensity of my frustration, but I'm worried it might come off as violent or bad optics.

For example, I have one of those shirts that depicts Luigi Mangione as a saint (in like a Renaissance oil painting style). Could this be interpreted as an endorsement of murder?

I want a sign that says, "Hands Off! or Heads Off!" With a drawing or silhouette of a guillotine behind the words. Is this too much? Too violent and threatening?

I'm ready to follow all the advice on how to protest peacefully and safely vis-à-vis action and behavior (less making sure I'm unidentifiable), but I'm not sure where we draw the line on the content of our speech. I don't want to make us look bad.
