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 ?
for most they are very disconnected from reality, just what they see on the internet, being more so raised by it then even their parents. And social media is very good at targeting those more vunrable people becuse social media thrives off of discord
