I guess the cringe comes from the PC moment of a 50 year old woman, even The Cavalry, taking down a fighting man in his prime. Perhaps the Berserker staff made her into a Buffy, but we would have had to come to the conclusion on our own from seeing that particular episode.
Ward might be stronger, but May is smarter (well, except when it comes to relationships). She's had at 10 more years on Ward, not including anything her mom taught her.
Yes, absolutely. There was nothing "PC" about this. Ward was actually knocking May around pretty soundly. In terms of raw strength, he clearly outmatched her. She only got the edge by outsmarting him, by using the nail gun to immobilize him and incapacitate him with pain so that she could then deliver the knockout blow.
And that makes perfect sense. That, or so I gather, is how women are trained to defend themselves against male attackers: by fighting dirty, looking for any opportunity to inflict incapacitating pain, because just outmuscling them isn't an option. That's not "PC," it's basic survival.
