I believe the main things which have been abused, are our intelligence and our vocabulary.
My intelligence informs me that the courting, mating and reproduction rituals of humans, have been going on from the start.
My education and knowledge informs me that some of what we are calling "harassment and abuse," are elements of that courting, mating and reproduction ritual.
I am NOT justifying legitimate bad behavior, but I am suggesting we need more definitive, accurate labels.
There are two genders involved with the biologic courting, mating and reproduction rituals, not just one.
