Autocracy and fascism are forms of governments that we’ve always flirted with. Woodrow Wilson promoted the KKK. Corporate leaders wanted to overthrow FDR in the 30s and install a fascist government. The Red Scare and protection of segregation in the 50s had elements of fascism as well. Japanese Americans and Native Americans were either put into camps or reservations, with native women being sterilized up to the 70s. Now we have Hispanic immigrant women being held in detention camps and being forcibly sterilized. GWB joked that dictatorship would be a lot easier, as long as he was the dictator. I don’t think he meant that, he was just being stupid W. Trump of course is much more serious about several terms in office and waiting to see what happens in the election.
The system only works if citizens and people in power care and pay attention. Sometimes the people care and sometimes not (WW2 camps, Jim Crow, reservations) but so far we haven’t fallen over the edge. We are in a lot of danger right now but nothing is carved in stone. The good news is the military leaders say they will not support Trump if he refuses to leave if he loses the election.
