Jordan Peterson has made the observation that interaction between males (if things get tense) always carries the implicit threat of violence. Which helps to keep things calm in many (but not all) cases. Because both males realize that "the other guy could start swinging". And so there is an effort to avoid that outcome.
But it's different with women. The rule is that you cannot attack women. And women know this. And so some women will push, and push, and push without letup. They feel unstoppable and invincible. Because they KNOW you won't start swinging. And that's how they get totally out of control.
...so it was much more pleasant to apologize/accept apology than to cause a possible regrettable situation.
