I did not ask for your personal evaluation of me as a person and so it is not relevant or welcome. Perhaps you should look inward and ponder why you feel the need to analyze others when they aren't asking for your opinion on such matters.

And that is all the answers should focus on.
In my opinion, nothing wrong with self-defense. See:
http://www.dhammawiki.com/index.php?title=Self-defenseIn the Vinaya, Suttavibhanga, the 92 pacittiya (rules entailing confession), number 74 states:
74. Should any bhikkhu, angered and displeased, give a blow to (another) bhikkhu, it is to be confessed.
The factors for the full offense here are three.
* 1) Object: another bhikkhu.
* 2) Effort: One gives him a blow
* 3) Intention: out of anger.
Non-offenses: According to the Vibhaṅga, there is no offense for a bhikkhu who, trapped in a difficult situation, gives a blow "desiring freedom." The Commentary's discussion of this point shows that it includes what we at present would call self-defense; and the Commentary's analysis of the factors of the offense here shows that even if anger or displeasure arises in one's mind in cases like this, there is no penalty.
Summary: Giving a blow to another bhikkhu when impelled by anger, except in self-defense, is a pācittiya offense.
And another important point to the above is that that is the rule for monks. How much more leeway might lay people have? Not to kill of course, but certainly protect for self-defense.
