A lot of (justified) sarcastic responses. I’ll try to give a productive answer: do you have a political issue you’re interested in, particularly a hot-button issue that’s in the news a lot? Find the organization on your side of that issue. They will host a protest/rally at some point.

You could just be the guy that has a “LOUD NOISES” poster at the protest, or, to put this in meme language, Rob Lowe in the NFL hat.
