I've studied fascism for many years. The most effective way to fight it is, for example, how Oswald Mosley was defeated in the UK. When a show of force is made by the fascist right, it needs to be countered with a stronger show of counter protest. The US lacks the appetite and intent to fight it.
Btw, I am nearly 60 years old and I fought with fascists on the streets since I was 14. There were never many Nazis in Germany but they are loud and they are always looking for a fight. Sadly, now they are as strong as they have never been since WWII (about 20% in elections)
Yes. You are absolutely right here
