well ive only fought in the ring when i used to train with these mma guys.
they were always better than me so it never ends well. but there was one time i was working the heavy bag and some white dude called me a stupid jap, and made a pearl harbor comment. i then proceeded to take him down and i started to punch him, i only hit him once on the face, then my friend who was holding the bag pulled me off.
one thing i learned from the mma training was that tae kwon do and karate never work in the ring. especially tae kwon do. only karate fighter ive seen thats succesfull is lyoto machida, but thats cause he's so damn good. and he's knows BJJ
