My 20 second rant

I was recently told that my bare-knuckle roots in karate lack realism because we dont strike the face with a closed fist. Then he told me about how realistic his mixed martial arts training was. I was going to go into a whole TIRADE ABOUT why he was incorrect in both cases, but I will keep it short. One, In my school we strike the face with open palms. It still hurts like you wouldnt believe. And second and most important to me is: YOUR TRAINING REQUIRES YOU TO USE GLOVES!!!! I HAVE NEVER WORN THEM IN A FIGHT, HAVE YOU?
