Demonstrate, but don’t mistake demonstrating for political action. You may find it gratifying to stand on a corner in Berkeley with a sign asking drivers to “honk if you hate fascism” and elicit lots of honks, but that’s as politically effectual as taking a warm shower. Organize people who don’t normally vote to vote for Biden. Mobilize get-out-the-vote efforts in your community. Get young people involved.
While I’d agree there’s a limit to the effectiveness of protest alone, it takes a certain kind of brain to think 
ing is the more politically effective move.
That’s nothing. There was a famous psychoanalist who wrote a book examining the psychology of fascism who had the terribly unfortunate name of Wilhelm Reich, which sounds like it should be the name for a thinly-veiled Hitler character in an 80s B-movie or something.
After writing his book on fascism, Reich went off the deep-end, tricked Albert Einstein into testing his wacky sex machine invention, became obsessed with the idea that the government was trying to kill him, then got himself arrested by the feds and died after a few short months in prison, and became the inspiration for one of Kate Bush’s most recognisable songs.
His son wrote a book about the whole thing and it’s an interesting read.
