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 ?
Reclaim patriotism. Republicans love to wrap themselves in the flag, progressives need to do the same thing. It’s just a piece of the whole, but seeing pics of the LA protests with Mexican flags flying - that doesn’t help bring American voters to a cause.
Seeing a lot of flags in the No Kings protests was very satisfying. We have to take genuine patriotism back from MAGA faketriots.
