Great post, as always your objective and see a bigger picture.
I must confess that I mostly speak from work related situation, where you can’t walk away (well with certain exceptions) sorry for the narrow minded view
You are so right in your comment “Has anyone ever heard of running away? It’s a hard thing to do, but to use another aphorism “discretion is the better part of valour”
One British definition of the use of force is:- the minimum force required to ensure the return of a safe situation” So given a situation, was running/walking away enough to ensure a safe situation? If so, then violence would not be justified. (Provided one was able to get away)
Midnightcrawler, absolutely agree, seen it loads of times, both parties in the full belief that they have been slighted by the other.
