I think a lot of ground can be gained by being nü-atheists but for the empire instead of religion. Liberals will say “colonialism, imperialism, neo liberalism” this and that, using all the right words, so why are you trying to save that shit by voting for Democrats?
Liberals respond better to smugness than bullying. Just lord it over them and wait a few months to be right about something (as always). To well-meaning libs, don’t be mean, just have the “that’s ridiculous, fundie, but you’ll figure it out, bless your heart” attitude and it’ll work itself out.
Hopefully, but if not, it’s not too crazy to start one on .ml or something. Fediverse shouldn’t be too crazy of a sell to actual computer nerds. They probably wouldn’t like you posting about it in the open on the sub (if they were cool they’d straight up migrate), but if you have a relationship with anyone else on the sub you can probably ask them to help you get it off the ground.
