The best course of action for us, I think, is to organize. Into innumerable groups that cooperate on a general forum on what we agree on, where we can cooperate publicly and privately as we see fit. Pledge to do something if a condition is met or not, organize into private groups, etc. The federation would be key so the government could not take down the entire whole with a pretext the first time there is a crime alleged. Or their own agent sends child porn to another agent and then they discover it and use it as cause to take down the whole.
So any protests we go to, do not just go march, sign people up into these groups, onto the general forum to join the groups. Obviously we need the actual development of that, but it could be done by the same people doing this fediverse it's the same concept. This way the government and big business could not get their hooks into a limitless number of new instances that could be made when they corrupt existing ones.
But we actually agree with most of the right wing on a great many issues, it is only because we live in different realities, and listen to different influencers, that we are at odds on some of the most important issues. Like the Base Issue, that working people shouldn't get screwed by the Rich without their consent. On such a site we could cooperate on such issues, and importantly could find and groom political candidates to take the candidacy from doomed to fail aristocratic sell outs dooming us to fascism, themselves supporting the oligarchy, seeing their reason for being as preventing popular reform and thereby allowing the fascists to run as reform.
