I'm going to an event soon and the last time I was there there were some of those awful street preachers with megaphones shouting bigotry. They're a nuisance and nobody wants them there, but it's a public festival and evidentially they're allowed to be there.
I tried looking online (
)and most of the advice was stupid lib shit, ranging from, "Call the cops and tell them they're violating statute blah blah blah" or, "Just ignore them, you can't change their minds and engaging just feeds their persecution complex." Obviously the cops do nothing, I don't care about changing their minds or what they think I just want to shut them up. But I also don't want to get arrested and if possible, it'd be nice to avoid disturbing the other people further.
Most likely, I'm just gonna have to endure it, but I thought I'd raise the question for brainstorming bc it feels like a common enough situation that other people will encounter it too. Best I can think is screaming something back at them 
UPDATE: I ended up just wearing a bunch of pride stuff and then they weren't even there lol
If you're real sneaky you can take a seatbelt cutter and cut the megaphone cord if it has one.
This makes me think of something. I would want to try this out before I'd recommend it as a tactic but if you could induce feedback into their megaphone then it would be a way of interfering without the need to risk any trouble.
Idk maybe someone who has a knack for sound engineering would be able to weigh in on the best ways to do this.
I guess one limiting factor would be how close you would need to get to their mic but sometimes as a protest action tactic, doing something that really fucks with someone else's ability to achieve their goals where they know what you're doing, they know you're allowed to do it, and there's nothing they can do to stop you can bring an additional layer of psychological warfare to your game.
