Interesting. My sensei distinguishes between sport and 'do', which is more like philosophy. Same comment about not fighting unless you have to, in which case you kill them. Ichi go, ichi e.
So, "man" (definitely not 'ip man', lol), try that argument. If you fail, well, she's just looking for a fight, so give her one. Good luck.
Second thoughts can generally be amended with judicious action; injudicious actions can seldom be recovered with second thoughts.

Boxing (western) is also considered a martial art - a purely percussive one with legs being only used for defense (movement), but all the same, a trained boxer will kick the crap out of a brawler pretty predictably.
Martial Art merely means systematized combat training. How it's used is another matter. Sifu Lale refused to train anybody for tournament fighting. None of his students ever won a medal or a trophy. On the other hand, he would randomly attack with various weapons including naked blades, wait for and evaluate your defense, then step back, smile and say "see, it works." He also encouraged us to use objects that we commonly had in our hands as weapons. Taught me to use a coffee cup, pencil, lit cigarette, keys, etc. as weaponry, in addition to the spear/staff training I was doing.
BTW, I'm getting a distinct whiff of troll.
Today she made fun of me what a coward and wimp I am the whole day. Now I am gonna meet with her and I will show her where she belongs to!
Honestly I find it cute. Try betting with her...
