At the risk of explaining the joke, you're not far off. Become an organizer at your workplace/apartment complex/community. Creating working class solidarity is the best way to fight against fascism. If you have extra time on your hands, you can volunteer at your local polling place, join a local group of antifascists that infiltrate fascist communities, or lobby government to make changes like making it easier to vote. There's a lot of options, but none of them are particularly easy to accomplish.
