Just some ideas:

• try deprogramming one of your MAGA relatives
• boycott the big evil corporations
• eat less meat, drive your car less
• VOTE in every election
• involve yourself in your community
• help in local election campains
• maybe even involve yourself with a new local chapter of DSA? (I don’t know how it works in the US on a local level)
• complain
• If you’re up to it, throw your sabot
