Or you're potentially a psychopath.
How people react to certain stimulus can be either acclimatized too over time and having repetitive adrenal dumping trained out of them.
My first parachute jump I was less than cool , calm and collected but after doing a few handfuls more it becomes normalised.. no more panic. No more adrenal dump.
When we used to teach women combative responses for self defence we used to intentionally get into their faces , within their personal space and use all the colourful swear words one would expect ( and more.. ) from an aggressor - the idea being to approach the tolerance trigger level of where one panics from nasty words and train that adrenal panic response out of their thought / reaction process.
I think the response would say more about where and how they grew up than it does about the instructors or their teaching.
I met one of my old primary school teachers recently; she's now 86, still sharp, still has all her marbles. Reminiscing about the school, Miss W. said, "It was a hard school, it was an area with a lot of hard people, hard choices", another friend who has spent his working life in creating guidance and opportunities for disadvantage youngsters, breaking the cycle so to speak, said, "There was, and in some instances still is, a culture of predation', in the area. Aggression and violence was normalised.
Those of us who refused to be 'predated' are still (too) quick to anger, quick to respond physically, quick to spot and use the defensive weapon. It wasn't so long ago that one of my childhood friends who still lives near my sister in law, faced off an intruder with an iron. He's going to carry that scar for the rest of his life. A. said she was shaking afterwards, but at the time, she just handled it.....and the rest of the ladies in the company, well we just nodded in understanding and quiet agreement, told her she'd dealt with it properly, and every one of us will remember his name and who his family are.
Not every social issue is resolved with police involvement.
Realistically I know that that quick response is not really a good thing, not in a peaceful society, but for many that's their reality, and their reality says that women are not as strong as men, that if you don't defend your stance, then you'll not be on your feet to make it.
I don't think that fits any rule of three though; it's kind of a hardwired into some kind of 'twitch' response.
We/they don't rise to normal shouting, or someone losing the rag and being offensive, but there's an edge, and if that's caught, then they're dealing with things before they'be taken time to think through any consequencies.
Scream and shout at us and we'll ignore you, walk away, you are in no fit state to talk with.
Touch or threaten us with physical restraint or harm and that's another response entirely. It doesn't need to be a knife to be a weapon.
We were angry at the social abuse heaped upon the Dundee teenager recently, wondering where the adults were who ought to have been defending the girls, but we were laughing too, in total admiration of the lassie's gumption, good on her....and admitedly impressed by the strength of her knicker elastic... she managed a knife and an axe down her back waistband.
It resonated.
I think that says more about our society than we might like.
