Done. Now what? Vote for the "grab 'em by the pussy" guy? This is the not a hypothetical. What the fuck can I really do to effect change? Because it is needed.
e: Full disclosure, I voted for Biden because he was better than the alternative (bad vs worse). Now, he is directly supporting genocide and I'm faced with worse vs worse and will not vote for him again. It's easy to snark and meme behind a keyboard, but what can a regular person in this country do?
I can't answer for you, but connecting with like-minded people, learning as much as possible, and doing as much as we can to destroy the U$ empire seems like a good starting point.
This election is fantastic to show how little functional choice the people in the U$ have - not only are both candidates senile, genocidal, rapists, it's impossible to vote in any candidate who will effect real positive change (in any position in the government).
Apologies for sounding snarky, by the way. I see that you have spent some time thinking about this.
That kind of frustrated atomization is exactly what this system counts on to keep doing Horrors Beyond Our Comprehension. You're not alone, even though they want you to feel like you are. Find some local leftist organizations that work on things you care about, and get involved. Food Not Bombs has lots of local chapters, and is often a good place to start for folks, but there are lots of options. The point is just to connect with others and start actually working toward a better world instead of being frustrated at home.
Join a leftist org and go from there. See what else you can do. I'm sure people here would be willing to point you in the right direction wrt USA orgs.
