Protesting with a sign and snarky message doesn’t do much. Everyone agreeing to do one simple (non violent) thing would work much better. It has to be just one thing though. The “don’t buy anything” day is ineffective and confusing.
“No kings” day should be more like “No Kings & uninstall Twitter/X” day. At rallies, people could give advice on how to delete their accounts on that platform.
Then at the next rally, it’s cancel Amazon Prime.
Snarky signs still welcome of course.
It’s the organization and collective action that are important. The protest is just a chance to demonstrate how many people are aligned on the topic enough to spend the day proving they can’t be ignored. You have to do the organizing and action outside of the protests too, just be careful about who you trust.
