This sounds silly but I sometimes wonder if these young women have had a diet of media with physically strong, powerful women that can beat up men with no problem. Think Buffy, Black Widow, Captain Marvel, etc.
Do they believe women are stronger than they actually are and people who say, 'wait a minute, men are stronger than you' are just saying women are weak and that's why they react so strongly to it?
I hadn't thought about the on-screen change in the portrayal of female characters. That could definitely play a role. I'd say that's a controlled environment. The ecological validity is essentially nil.
At the same time, we're told there's an epidemic of sexual harassment at school and in clubs. I actually don't believe it's worse than 30 years ago, until we add the internet. There, I think we have high reflection of the real world..but it's "online" so not real in many ways. There seems to be a massive disconnect between, for example, someone acting out their kink/fetish on the internet and the understanding that it's in any way related to real life.
It's rather odd that this generation claim to be the most sexually harassed, yet don't think what men act out in real life is in any way relevant to their own real life, if a mobile phone is in their hand/on a stand.
