I have a leftist friend who's a historian writing a paper on how the right is so successful at organizing and why the left sucks at it. Trying to help them gather sources. The more scholary the better.
She's particularly looking at right wing paramilitary organizations (proud boys, 3%s ect) And why the left has trouble forming their own.
Edit: question might have been a bit ambiguous, we all know a lot of the basic reasons for this, what I need is the type of thing that can be used for an academic research paper. Interesting discussion is still good though so have at it.
I think the premise is flawed, the left has absolutely organized successful violent opposition to fascists. Read No Fascist USA to learn the story of the ARA kids in California in the 80s and 90s. They went to war with the fash and won. Left wing militants just don't go around battering random black people and trans people, so there's really no incentive from a sensationalism perspective to report on them.
