Here we go: Me, with the unpopular perspective. I started karate in Hawaii as a kid in 71. We didn't dare lose our tempers or show disrespect to decorum, or we could count on getting the crap knocked out of us by our seniors. It was expected; it was their job. If we got out of hand, and cold-c0cked for it, we took it as the cuffing it was, and made a note not to do that again...unless we wanted another beating.
Now, we live in a sue-happy world of uber-political correctness, where the old ways immediately brand someone as a brute, a fiend, an out of control maniac requiring justice and incarceration, etc. I view this as a lesson in respect for the process. I doubt this kid that got thumped went home and thought about why he got spanked, but he certainly should have. It was this type of corporal, martial punishment that kept karateka on the straight and narrow for so long, kept the punks out; and it's the absence of it that leads to so much of the shenanigans we see in open tournaments now.
Time was, if the ref didn't pop you for being a putz, you could count on getting a black eye, fat lips, bloody nose and cracked ribs during the next class session after the tournament, from your own guys...Sempai and Sensei driving you into a corner and continuing to kick the crap out of you even after you've indicated surrender. Often followed by a quietly menacing admonition, "Never embarrass us like that again."
Now, coaches and instructors can be heard hollering poor sportsmanship from the bleachers; kids are instructed to take cheap shots to take the wind out of an opponents sails; and so on. The idea of an honorable match where two mutually respectful combatants bow in, fight clean, and congratulate each other on the good stuff are too far gone for me to feel sorry for this kid getting clocked by a senior. Karate begins and ends with courtesy and respect. If the seniors don't enforce it, who will?
