I do it fear it I think it is stupid. It is like not wearing a mouthpiece and punching each other in the mouth. I have not tried that either but it is not good training. Is that ridiculous?
What is ridiculous are people claiming to really spar with no gloves or protective gear. They may move around and slap at each other oh wait weren't you one of the guys who that that was good sparring? Now it makes sense you are not really hitting each other but call it sparring.
