I think the Democrats are not a great political party. I'm registered independent. They are the only mainstream political party for pursuing progressive change that we have at the moment. We have to take our chances with the Democrats because it's the clearest path to a better future that we have.
We do need to adopt socialist policies as a country in addition to that though. If we stick with neoliberalism then we are going to keep having this problem. The fascist movement will inevitably grow as the wealth disparity gets worse in the US. People are going to be looking for solutions to their problems, but neoliberalism inherently denies them the tools to fix the systemic issues they face. Neoliberals cling to civility politics and value property over justice for people to name a few. Fascism will provide them with easy, but incorrect, solutions in the form of out-groups to hate. The answer to our problems is socialism, but we need time to convince people.
I know it's a long shot, because people are effectively conditioned from living in a neoliberal society to reject socialism without any evidence. But we have to try. The only way this gets better is convincing people that socialist ideas have merit while neoliberal and fascist ideas do not. People's lives depend on nations developing and maintaining inclusive political and economic institutions. We are going to need to have this ideological reckoning at some point, so we might as well have it sooner rather than later.
Trying and then failing presents the same consequences as not trying. So we might as well do it now.
