join an org. We know electoralism doesn't work, we know adventurism doesn't work, this can only be stopped through collective worker action. The power of the proletariat comes from our direct control over the means of production. If we organize we can block arms shipments, strike until our bosses drop their contracts with Israel, etc. I'm a tech worker so I have joined a local group called "tech workers for Palestine". USPCN and other orgs are national. You may have to do some searching, but there are likely people working together in your area.

Social media is okay too. In my estimation the time for "raising awareness" is past. Everyone who's going to get the message has already gotten it. Now is the time to fight. Everyone feels like you, horrified and powerless. We have to give people something real to do, something that makes a concrete difference. No more going home after a peaceful rally wondering if it'll convince anybody. People should go home knowing that the gears were stopped even if only for a moment. That certainty is what will push new people to action and make them keep showing up. As politically advanced people, our task is to start the feedback loop by channeling popular rage into those first productive actions.
