I think progressives never thought about this because we banked on immigration and demographic change allowing us to win culturally and electorally but the issue is immigrants tend to be overwhelmingly male, that is how Trump won actually he won over a lot of Hispanic,Black,Asian and indigenous men who feel humiliated by a new culture, economy and world.
So what can we do rhetorically and policy wise to win more young men over ?
Frankly the online stuff doesn’t get to me, but I could see how the generalizations could leave a person succeptible to a narrative. Online interactions tend to have some people taking the easy way and espousing simplified generalizations and on the receiving end are a lot of people that may take the online stuff too serious.
The false dichotomy works because those are the two loudest viewpoints online, that men are villains without a clear path to being accepted or to embrace horribly harmful toxic masculinity to get some screwed up sense of belonging and success. Young men online are at risk of being ill equipped to navigate the nuance That tends to be quieter over the noise of the two more passionate perspectives.
