I don't see random girls hitting boys just because they can. They are always avoiding guys because of this fear society putted onto them so they are obviously not going to retaliate by hitting since they are intimated by guys and trying not to get raped all of the time. Yes, women abuse men and men abuse women. But there are also boys getting away with hitting girls because of the boys will be boys bs and so many men being excused with abuse. Also self defense isn't hitting the attacker back.
