There is an aspect of the situation that you’re perhaps not considering, and that is the other person in the conflict.
I’ll tell you a story that, although it isn’t quite the same situation (mainly because I was asked for help), still has bearing on the topic.
I worked as a bouncer for a while at a place whose main bartender, “Danae,” was female (and she also worked as a bouncer there on live music night, when I wasn’t available). Danae was tough and well experienced in dealing with drunk guys, but she was ALSO little and blonde and didn’t LOOK tough.
One time I came in on my day off to pick up my paycheck. There were two guys at the bar who were drunk (and must have come in that way, because she was really strict about not over-serving people), she was telling them they couldn’t have another drink, and they were NOT taking no for an answer. She was in the middle of telling them to get the hell out, and I could tell from the volume and tone that it wasn’t the first time she’d said it. They weren’t budging, were in fact making snide remarks about how much they looked forward to her grabbing them to throw them out, etc.
Danae caught sight of me and said, “Hey Troy! These guys are being assholes and I told them to get out.” Knowing my part to play (and yes, I understand the OP’s characterization of it as a piece of theater, even if some of you don’t seem to), I came over, loomed over them both from behind, and said in a voice even deeper and growlier than my usual hot-fudge baritone, “Then what the hell are they still doin’ in here?”
They turned around, looked at me eye-to-sternum, looked up to where MY eyes were, and slinked right out.
Here’s my point: Danae and the OP understand what some of you don’t seem to, which is that even though a woman may be PERFECTLY capable of taking care of herself, there are certain MEN who think they don’t have to listen to a woman or take her seriously, and will only respond to… yes… testosterone. If Danae had had to deal with those douchebags herself, I guarantee you they would have wound up just as thrown out as they were by me, but it would have been a much bigger hassle and might have gotten violent, because there ARE self-important cocknozzles who think women aren’t entitled to say no to what they want.
And I’ll tell you what Danae DIDN’T do afterward: she didn’t say, “You men are a bunch of chest-beating gorillas.” She said, “THOSE GUYS were assholes - THANKS, man.”
And I said, “No biggie – I was just saving them from YOU.”
