It's an important question.
Looking back to the journey women went on, it started with women saying louder and louder No, This Is Not Ok. It's not just a laugh, it's not boys being boys, it's not fair game if we dress like we are up for it. That moved the dial so the public and private conversations could happen.
I agree women have our bit to do, obviously by not sexually assaulting anyone ourselves (though I hope I don't have to tell anyone here that!) but also by not minimising "hen-night" type groping as "just a laugh" and making sure daughters understand consent applies to what they want to do to boys as well as what boys want to do to them, and sons understand they have a right to say No.
But I think whatever women do, it won't be taken seriously unless men change the "lucky boy!" culture around it.
As long as men get the message from their peers they should want and take advantage of an attractive women sexually assaulting them, laugh at an unattractive one with their mates (but maybe take advantage anyway, what the hell), but either way definitely not find the experience in any way upsetting or traumatic or frightening or degrading because those feelings are weak feelings and real men don't feel weak because of anything a woman could do, this won't be taken seriously. Men won't object even though they should, and so it will continue to be played down.
It would be great if that reddit thread is the start of men saying "this happened and no, it didn't make me feel lucky or great. It made me feel poweless and scared and ashamed and I've never felt 100% ok since" and feeling like they can have sympathy for each other rather than looking down on men who admit that a woman had the power to make them feel like this.
