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 ?
People gravitated twoards progressive policies after the great depression, before the cold war.
The cold war was the first time the US made it legal to use propaganda against its own citizens
So basically, people will support progressivism as long as they are educated and don’t have their brains raped by neo-religious and capitalist propaganda from childhood.
It would also help if men weren’t the “target” of every liberation movement.
When you grow up learning everyone thinks you are racist and sexist because of the way you look then that’s real bigotry.
Men don’t get sympathy, neither do whites from non whites.
Starting there would be easier than stopping the propaganda
