Harassment is about throwing people off their game.

Ask professional athletes if that's true.

It's the same dynamic for women in the workplace or other areas of their lives.  Either the people harassing them, be they male or female, want them to be off-kilter so they are less effective or the harassers are having too much fun being abusive to have empathy if they put their targets off-kilter.  If the bullying is bad enough, then the disorientation of the targets is also amusing for the bullies.

You'd think that more male athletes would have thought of this parallel to their lives by now, but sports culture doesn't encourage them to think of women as if they are people.
