(Please know that I do not condone violence at all. I do believe in protecting and standing up for yourself and that sometimes Newton's Laws (and not the doctrine of nonviolence) govern the response/reaction.)
But all of this (especially in conjunction with my boxing lessons) have made me think about fighting in general. So many martial arts philosophies and disciplines (such as Aikido, or even taekwondo) begin with the sentiment that fighting is a last resort. So many religious philosophies believe the same ("turn the other cheek"; even the Koran promotes exhausting all diplomatic means before engaging in violence).
In other words, just because you possess the ability to fight doesn't mean you're walking down the street picking fights with people just because you can. Just because I'm learning to box doesn't mean I'm a violent person or that I am looking to fight (though I do love sparring).
But it does teach you what to do when the fight comes to you.
We've all had fights come to us.
