How do you seriously fight fascism and don't say just vote?

One way I've been trying personally is just gathering as much information as possible and remembering it. I've always been super bad at history and biology because of my resistance to memorization, but I'm slowly keeping up while trying not the get burnt out.

Of course, after I have enough info, that'll inform me of what the next move is, I hope, because if I do anymore now I'll just crumble
