I live in Portland, where many anti-fascists believe that the lesson from 1930s Germany is that Fascism needs to be fought in the streets. My vague recollection of history class is that the street brawling ended up helping the Nazis. What is the academic consensus? Was confronting fascism on the streets a heroic last stand that happened to fail, or an integral ingredient in the success of the Nazis.
I would probably refer you to the answers given in the following thread by /u/commiespaceinvader and /u/kieslowskifan from 3 years ago:
I believe this via /u/crrpit may be of interest - an answer relating to similar tactics with regards to countering the British Union of Fascists in the UK in the 1930s, and the Battle of Cable Street (a famous street confrontation between antifascists of various stripes, the BUF and the police)
(I was going to attempt an answer wrt Cable Street but this is much better than what I could do, Mods please remove if this isn't allowed)
