The "honest mistake" trope is not sexual harassment. Now that I know more about how the world works, that story was clearly a PR push to de-legitimize the complaints of both the particular people accusing these public figures at the time, and anyone who might try in the future.
I very soon had a fast primer on what is real sexual harassment. One coworker at my first job out of college was constantly haranguing another. Overt sexual advances that were always met with "that's just <him>. It's just a joke." It made me uncomfortable just to watch it. I know it made her uncomfortable because she would lock herself in her office and cry at least once a week. I don't know why she confided in me about it. I begged her to file a complaint. She was probably right that it would do more harm than good. I complained to my own boss and got told I was too young to understand. I suppose I was too young to understand, but only because I had not yet reached the point where I rejected any authority figures who told me shit like "you're too young to understand" at 22 years old.
The guy did this in the open, during project status meetings. This wasn't Uber or UploadVR or whatever other Silicon Valley brogrammer startup we're going to tsk-tsk "boys will be boys" and never actually do anything about. This was an established engineering firm, with a very strictly worded employee handbook, and an HR director that literally looked the other way.
So I don't want to hear anything about it not being systemic.
I've personally never found sexual talk of any nature in the office to be comfortable. I've had gay bosses hit on me. I've had straight bosses "jokingly" touch me inappropriately. I've had female bosses make jokes about my love life. Sat by while coworkers traded stories about sexual conquests. Even if the sexual advances are towards someone else, if they make you uncomfortable, it's still sexual harassment.
But we've had this trope that it's some sort of attack on lonely men who take a risk on finding love. And I think that active misdirection has not only (obviously) harmed so many women, it's harmed quite a few men, too. Probably most of us, in some way.
It's not "getting along with a woman at work and ask her out and she rejects you." It's about creating a hostile work environment. Anyone who can't tell the difference has got a serious problem. You do not have to put up with being made to feel uncomfortable like that at work.
