Yesterday, there was a documentary movie on German's private TV station Pro7 about Nazis. An actual Nazi confirmed live on camera: yes, deplatforming Nazis (and that includes them losing jobs, family, friends) works and is a huge source of pain for the movement because many people don't hold up to that pressure and leave.
Just imagine how big the rallies would be if there was no social pressure on not being Nazi would no longer be there... at the moment many attendees either don't give a f..k about how they are perceived, or they relish on that being accepted in their social circles.
