You know what does help people? Community building. Feeding people. Organizing workplaces. Forest conservation. Building housing. Forming tenant unions. Organizing anti-ICE demonstrations. Etc.
Actions solve problems commensurate with the time and effort it takes to perform. Voting takes very little effort, and solves very few problems. Community organizing takes a lot of effort and solves lots of problems.
Vote for whomever you want, I'm not going to demonize someone for voting for Harris. But like, that should be the smallest contribution you make by at least two or three orders of magnitude.
