If you can't find a leftist book club, make one! And pick a book that resonates with your personal experiences, it will resonate with others too!

Or an essay!

Or a comic!

Or a show!

Or a movie!

I've started one with some friends and it is the most catharsis I've had in years. I also am involved in an org too, so it isnt just the "oh cool im actually doing something" itch being scratched. I think it has something to do with doing intellectual labor in a non-atomized setting. The fact that the book is marxist and is allowing us to articulate profound feelings we've always had about society and our place in it is a major bonus.
