@Pepperm1ntsSarcasm aside I mostly agree with you.
Strong effective counter protesting and exposing those on the fringe does work.
Intimidation and violence is what emboldens people.
I think the fact is that everyone knew they had eyes on them and for the most part didnt really get into any fights, also a lot of the big names in the alt right includinf spencer, anglin, cantwell just straight up decided not to go because it was 'bad for optics'. The only 'leader' there was the fat, arrogant, borderline 'alt lite' Jason Kessler who is unpopular in his own circles and a total nobody to everyone else.
It was a pretty toothless rally from the jump.
