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
Get some friends, play some vuvuzelas right in front of them. They're cheap and plentiful and drown out any other sound.
I like this plan the best. Just get right to the point.
You can instruments at home, too. Put dry beans in plastic bottles to make rattles! get a heat gun and some pvc pipe and make different kinds of horns. Bang pots and pans. Lots of stuff.
