Just because someone bashed you doesn't mean the situation calls for a gun fight.
Taking the UA Reminder as completely black and white, or many of the rules as black and white, is being intentionally obtuse.
Bashing =/= shooting someone. Nor does it equal lethal force. Punching someone can also be considered the intiation of a fight, but if two generals getting upset in a meeting and start trading blows and one of their guards just gun them down, that guard is getting absolutely decimated in a ban. Context is widly important. As I have said ad nauseam, contextualize!
I am told there were 15~ odd people in the situation you were in, and everyone has told me nothing in the situation required a gun fight to occur. Starting random gun fights because you don't want to RP (arrest, yelling, reports, etc.) really isn't our problem.
