So basically when low status / unattractive men flirt with a woman it's sexual harassment, and when high status / attractive men sexually harass a woman it's flirting.
I'm a fairly good-looking guy and I've shot 50/50 with women at best. Never been accused of sexual harassment, but I can think of times when a girl went from being interested to not being interested (usually when they found out I was a student at the time) and suddenly I was "overstepping" even though I wasn't treating them any differently from before when they were into it. If that makes any sense. Like I've seen the transformation in real time from being seen as high-status to low-status, and the complete change in attitude that goes with it.
So there it is, the crux of all this that nobody wants to admit. It's really more about power than anything else. Attract high-status men while also wielding power over all the ones you don't want (otherwise you have to put up with them talking to you, boohoo).
