I understand and agree with what you are saying here, but the rest of your post left me a little unsure. I don't think that asking this question necessarily implies that one is going out looking for fights to see what he can get away with. Bruce Lee did this, and while it may have made him more confident in himself, his early years say little of his respect for life (thankfully that changed as he got older and matured in the arts). I for one do not go out looking for trouble, but the sad state of affairs in my hometown sometimes brings such circumstances to your front door. My basic philosophy is this...I now practice the MA's for self-defense purposes, and if a person is approaching a combative situation with me, and it is feasible and an intelligent thing to do, I will try to avoid the confrontation. However, if it is not the intelligent thing to do, or if it is not avoidable, then I will do whatever is necessary to defend myself and my family. Especially if someone breaks into my house threatening their safety...there is no wondering about how much force needs to be used.
