The ones that come to my mind are:

• 1. Donate to socialist groups and causes, especially ones based in your local community. (Food banks, libraries, arts organizations, community legal funds, or individual mutual aid requests.)
• 2. You can phone bank for socialist politicians in order to help them get elected. You don’t have to be a local to do this. I recommend Kat Abughazaleh.
• 3. If you have a skill that can be used remotely from within the home, consider volunteering it to socialist organizations.
• 4. You can create socialist content, but understand that your stuff is going to be algorithmically-repressed to some degree on any corporate-owned social media.
