Is it ever okay for a man to raise his fists to a woman?

[Dave Hughey]

It's all about necessity and levels. You want to pacify a girl? Why? If you really think it's necessary fine, but don't go over board. I'm sure a simple arm lock would suffice. Maybe a flying triangle.

Seriously though, in any circumstance it's weak to want to 'get at' someone who is clearly weaker than you. Man woman or child.

I agree. I got attacked by a lady with a butcher knife. She cut me pretty good. Scared the shit out of me. But I broke her knife and put her on the ground and sat on her until the police came. I shiver whenever I think about it.
But most women (and children) are much weaker than most men and even if you are attacked, you should only use the force necessary to keep them from harming you. You should never use force for any other reason, IMO.
