It's not just generational, sadly. I've run across plenty of men my age and much younger who feel that men and women can never *really* be friends, and that we're just so different that there's no intersectionality of perspective or experience at all. Heck, how many threads in the writing forums on AW have been started by younger guys who want to know how to write women convincingly. It usually comes down to thinking that women are completely alien.
At least there's conversation about this today. When I was young, I couldn't quite articulate how upsetting it was to be objectified and to have my internal life and reality dismissed, though I tried. Most people, including other women, didn't get what I was trying to say and thought I was nuts, even offensive, for thinking about these things. People would tune me out or tell me to lighten up. When topics like sexual assault or harassment came up, even feminists (and few young women identified as such in the 80s) were still focused "taking back the night," not dealing with the assaults and harassment that happened in the light.
A friend of mine once said "it might have been better if we'd held off the sexual revolution until after the feminist one was complete." Perhaps that would have been impossible - they had a synergetic effect - but it would have been helpful to have society first accept "women are individuals whose life choices must be respected" before we got to "you can have sex with anyone willing." Because it seems a lot of young men grew up believing that women owed it to them to be willing.
