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 ?
As individuals, we can only influence our friends, family, and kids as best we can. Sometimes that’s not at all. We’re all now familiar with the trope of “Fox News ate my parents’ brains”.
This isn’t a game or a movie that necessarily has to have a happy ending. Sometimes shit’s just fucked. As long as the propaganda machine is in place, millions of people will be brainwashed.
