Boycotting corporations as an individual is obviously useless, but if you work in an industry that manufactures or transports weapons/ammunition/etc. to "Israel", you can educate your coworkers and help organize a strike or transport blockade. If not, you can try to educate those who do work in such an industry. If neither is a feasible option, attending protests and spreading propaganda in other ways might help radicalize others. You could attempt industrial sabotage (in Minecraft), but if you're in a position to do so, you probably work in that industry and can make better use of your time organizing
