The entire topic about "fighting" is vague, If there was a person with a knife trying to hurt you, you want him discharged as fast as possible. Pain or no pain, that person must be taken out with anything available, and that brings up an assortment of other possibilities. So really we need like 500 subtopics. lol. Fighting styles has a lot of controversy. I recommend learning and excelling at a group of different arts. because really you can take down a guy that's 4 feet taller than you in a matter of seconds if you know how. and ill shut up now
