But the harassment, in this case, is only a symptom of the sexism that is making its way into the very core of SV workplaces. Everything gets amplified when the perpetrator enjoys more power and the support of the boy club. This case is just one more demonstration that the problem is not the limits of propriety, but a very unfair distribution of power.
If someone hurts you, whether or not you will experience the offense as a dangerous threat depends very much on whether the offender makes the offense knowing they enjoy the protection of power, which allows them to harm people who don't.
It can't be a symptom of sexism, else I could not ever be accused of harassing a man. Yet, could be capable of harassing a man, or a man harass me. Or one woman another. And power amplifies it, or squelches it (one rarely sees a superior get sexually harassed, but it's not because a potential harasser does not exist). Harassment is to me, more a disorder, at least that's how I have experienced it.
People aren't sure any more if a compliment is going to be interpreted as harassment. Harassment meanwhile goes unabated, and as you conclude, may be getting worse.
