Difference is, We men are strong enough to walk away.
While it is generally true males are physically stronger than females (exceptions to every rule caveat), if she is armed, that levels the threat.
So if a female is threatening and attacking a man with a knife, I will support whatever reasonable force he uses to ensure his safety.
Same deal legally when one guy is attacked by three, the law from my understanding (iirc NOT legal advice) allows him to use deadly force and/or a weapon, as it recognises it as an equaliser in the situation to ensure his safety.
Surely you've had arguments with females who will not let go either and follow you.
Walking away is futile in that situation, as it only enrages them further.
Females primarily run on emotions, so when we reason with logic, it does not compute.
They're unable to comprehend facts that counter their emotions.
