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 ?
I am going to be honest, I think women need to be a a part of this. We are used to being right in regards to gender conflict because usually we are but one thing I agree with men on is that every woman says they want men to share their feelings more but many women lose respect for a man they see as weak.
Bell Hooks talks a lot about this so you can go read her.
I do not find that to be the case at all in my circles, it’s usually the guys giving shit to other guys for expressing emotion and the emotionally expressive people (including women) riffing them for back for being assholes. There’s certainly a song and dance to doing this effectively.
I don’t really think it should be a gendered expectation but rather an everyone expectation. If someone is being vulnerable with you that wouldn’t otherwise, don’t be an asshole. If someone needs to be called out for exhibiting rude behaviour to someone else, do so in the way that works for your circumstances.
