Couple of things:
- Revolution sounds good until it actually happens, and then it sucks. It unleashes all the crazies and the outcome is uncertain. And it tanks the economy.
- If you look at exit polls, people told you why they voted for Trump. Rightly or wrongly, they don’t believe he is a fascist, or at least that the US system won’t allow him to indulge his fascist tendencies. Again, I don’t know if they are correct, but that’s what most people believe.
- The majority believe that the wokism and identity politics of the left is a greater threat to democracy than Trump.
So, the answer to your question is that you won’t find much support IRL because most people don’t actually think they are supporting fascism. Time will tell if Trump is an actual fascist or just a blowhard. I wish we didn’t have to wonder, but there you have it.
OK, so what does this mutual aid look like? Are you talking about organizing armed resistance for when the Gestapo come for you? Or more like food-sharing for when the revolution comes and destroys the economy you don’t care about? I don’t have a sense of what you are getting at.
