one minute one is 'precluding' a possible violent attack on the street...the next instance could be popping your wife in the mouth for yelling about you being out too late.

Iím sorry but that isnít even a logical progression. One is a violent attack and the other is an argument. Unless there is a history of violence of the wife on the husband there should be no need for a pre-emptive strike. Even if there is a history, one does not go straight to violence. Using Leoís progression levels of self defense from a current thread:

1) Common sense
2) Avoidance
3) Awareness
4) Humour/light heartedness
5) Rapport creation
6) Verbal SD
7) Fence
8) Escape
9) Pre-emptive strike
10) Physical self-defense

I understand what you mean, but I donít agree with no pre-emptive strikes.
We should all take ourselves seriously...and then crumple that image up and toss it out the window.
