Now that KL's stepped down from moderation, he can be king of the flame wars.
Back to the notions of "old school" and who "should be in the ring at all", a lot of that is over romanticized, IMO. Sure, I don't want to appear unfilial, the old masters were great and all, but who of us is really qualified to say what the "old school" was like? Was it really that different? Or was it like this video? History can play tricks on your perceptions, tainted by your world personal world view. A lot of people want to imagine that martial arts is so much better - that fights should be so much cleaner. But fights are fights, and any of us who have really stepped into a ring know that while a clean, old school technique is all fine a dandy, I'd rather opt for the technique that scores.
The video looks fairly authentic - maybe the exact date is not correct, but who would bother to stage something like this as a charade? What would be gained? So I think that the validity isn't so much an issue here. Even if the date is off by a bit, it still stands as an interesting historical document for our field where few such documents exist.
It also shows us that when you rely on a right "stamp the seal" punch to heavily, you can get clocked upside the head real easy.
