My personal view on fighting is it should not be done unless to protect your family or preserve your way of life. If you think about the reasons why people fight it boils down to they want to prove either to themselves or to other people that they are superior to you by kicking your butt. If someone doesn't like you cause of the way you look or is rude and is being an asshole to you the best thing is to do is either walk away and not be bothered by it because whats the point it won't change anything getting mad over it besides your not gonna let someone ruin your time so let it go and move on. I have never fought and don't wish to unless to perserve my life or my families (when I get one). Even if they are chalanges don't accept because you have nothing to prove to anyone if you say you have something to prove to yourself then you are uncertain of your own skill as a martial artist and need to spend more time training until you are certain of yourself then you will not need to prove anything cause you are self sufficient in your art.
Walk on and be well my friends.
