I don't see the point of violence and I prefer to avoid it. I will never instigate violence of any sort, and I prefer to negotiate and try to understand the other person's perspective.
It is possible to push me to violence in self-defense or in defense of others. I've been in this situation when I defended myself and my sister against my stepfathers, both of whom were nasty individuals.
When I do choose to fight, I do not use any of the social rules. I go for eyes and genitals. I bite. I do not take any heed for my own personal safety, and I do not feel injuries. If it comes down to it, I am not a good fighter, but I fight like a cornered cat fighting for its life. There's no social posing and no yelling. I just detach from my emotions and carefully calculate where I will do the most damage, and then I do that.
Thankfully it has only happened two times in my life. Both times I came away with injuries that should have been very painful, but that I did not notice until later. My opponent came away convinced that I was psychotic. The first time was against my stepfather when I was nine and in a meltdown, and he pinned me to the floor. I did very little damage, but as far as I can remember I didn't stop fighting until I passed out. The second time was when my second stepfather messed with my sister. I never did land that kick to the groin, but I sure tried to. After that, he messed mostly with me, and I mostly didn't fight back.
I am not a violent person. I would rather be taken advantage of than hurt someone else. I want to understand even my enemies, of which there are few, and I have never hated anyone. That means that if I have to fight, the situation is probably rather extreme. I do not think I have much of a chance of winning, because I am a short, round, rather weak woman, but I am unaffected by either pain or social intimidation, and I don't use social rules. Think of what would happen if you tried to hold on to a feral cat. That's pretty much what you could expect from me.
