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 ?
I genuinely believe that more empathy is needed in both directions for people to come out of their trenches. Problem is, it"s hard to feel empathy for those who have no empathy in return. It’s a locked position reinforcing itself with every bad interaction. To break out of this we would have to listen and show that we care, while not getting the same things back. It feels bad. Unfair. Again, this goes both ways.
