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 ?
Help them to break down. Encourage them to be soft and show them that that softness is strength. So many of these young men are like this because they feel alone. We need to bring them together in positive ways.
