The profound uncreativity of fascism -- same as the Nazis: kill disabled people with official eugenics, kill people with differing sexualities, various crank right-wing theories instead of science, conquest for imagined resources, police state. Same response by liberals. No one learned anything, people on the right aggressively adopted fascist boilerplate and pretend not to know where it leads.
I had low expectations for people in general throughout my life and that was accurate.
