I like the gist of what you’re saying, but I think the narrative of “we did this to boys” needs to be revisited, too. As children, many of us were taught stuff that we realized was wrong when we grew up. For example, I was raised with corporal punishment, but I didn’t beat my child because that’s what I was taught.
If men are supposed to be mature adults, that also includes them revisiting how they define masculinity. And for the record, I know lots of men who don’t need to be drunk to hug someone and say I love you, man. You know?
Change has to start somewhere. As the quote goes, we need to be the change we want to see in the world. The question is — do they want to change? Many do and many have, but some don’t seem to want to. They’d rather stay stuck in 1965 roles where women “know their place.” Those are the ones I take issue with.
