cadnowyllt I am without question a seriously odd person, so guilty as charged.
However no I don't go into every interaction with women thinking anything like how I could come out on top in a physical altercation. In fact I don't think the though has ever crossed my mind once. What I was trying to shine a light on is the background in which all interactions between men and women operate on.
For example a lone woman is far less likely to come up and criticise me, if say I was in her way or some such. Also take the traditional role of getting women home safely, I've done it so many times in so many contexts I wouldn't be able to say how many. I've even done it a few times for men who were particularly timid. However most individuals see that as a "nice thing" and invariably it falls under interpersonal interactions where people will feel the need to reciprocate, thus advantage which was what I am trying to get at.
The actual reality of the situation at least for me is that if something bad happened to any man, woman or child I'd just been with I'd feel rightly or wrongly that I hadn't done all I could if I hadn't taken steps to ensure they got home safely after a night out or whatever. So I mainly do it to satisfy a neurosis in my own head, but even if I explain that to people they usually don't get it. In a way they are actually doing me a favour as I won't worry.
I've stood up to male violence several times in my life and it always scares the shit out of me. However the one time I came off particularly worse and got stabbed (luckily it was only superficial)! There was this absolute angel of a woman who cleaned me up, sorted me out when I was quite shaken and embarrassed, so if anything my attitudes since have been trying to pay that kindness forward.
However my point still stands being a non-violent man in a world with too many violent ones confers tremendous social advantage, especially with women.
