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 ?
Of course the focus is on women and generally LGBTQ+ people, as they are oppressed groups.
In its wider sense though, especially with the focus on intersectionality, it is for a fairer and juster world for everyone as the systems of oppression affect us all in various capacities.
