It really is surprisingly effective. So few people actually contact their legislators.
I set up a harassment campaign and got a few hundred people to contact a state legislator whose committee was holding up legalizing weed in my state and a few months later it was legalized. Agitate. Make a difference. Protesting doesn’t do shit, get all the people there to call their representatives and senate members - especially for state and local stuff, and you might actually get something changed. Or even better, send a letter.
I mean, yes, but grass roots and I’m not paid lol
