For starters, understanding that American fascism is not the result of voters simply not being informed enough. The idea that, if all Trump supporters simply had access to better information, if they all had better education, if they were exposed to the right argument... then they'd see the light and turn into democrats - is a supremely liberal idea. We need to understand that no amount of epic slams, no amount of late night talk show roasts, no amount of facts and logic will steer us out of fascism.
As we devolve deeper and deeper into fascism, it has been frustrating watching liberals flail to try and understand how the devolution is happening: is it because people are uneducated? Is it because of Joe Rogan's podcasts? Is it because of Russian spies? Is it because Trump has started a cult? Is it because Fox News? Is it because lead was used in gasoline 50 years ago? Is it because we use lead water pipes? Is it because of Ronald Reagan? All of this waffling to avoid the hard questions. I.e, "is it possible that fascism is the only logical conclusion a nation which was founded solely by white landowners to do wholesale on genocide on native Americans?"
If you fail to start thinking about this devolution into fascism in terms of history, class, and material conditions, you're always going to be hopelessly confused about the structures and frameworks that allow fascism to fester.
