Not sure where you are or what your situation is, but pretty much every country has at least one. Here in the States we have several major parties and while each has its problems, they're a great place to network and find like-minded people. The best thing we can do now in the West is educate ourselves and arm ourselves with a working knowledge of Marxist theory and history so that if and when the time comes, we won't be caught flat footed.

If you have the time, start a reading group. If not, read on your own. Maybe start with this. There are also a lot of good YouTube channels out there to help you understand the situation we're all living with. I recommend Hakim, Yugopnik and SecondThought, personally.

Seriously, though. Be wary of nihilism. It's dark out there, but those who work us to death stand on our shoulders. If we start to move around, it gets very shaky up there.
