Judo can be viewed IMO moreso as a battlefield art. Granted some of these are changes came about during WWII, but I think you'll see. Today when you step on the mat, you have once chance, the "Sudden Death". Then it's over. It's almost kill or be killed. Judo Shiai is hard. You're opponent is nothing more then an obstacle in your path towards victory. You wan to hurt them. You care nothing of their safty, save for the rules laid down for competition. They should know how to fall.
In judo we don't speak of "Ki" much. IMO Ki does exist, I've experianced it, but for most Judoka it's a non issue as it relates to our art.
I think it boils down to a few things from this mans perspective:
1. Judo is an art, but practiced as sport.
2. The name Judo did exist before Kano, but Kodokan Judo did not.
3. Judo when intorduced was new.
4. Many modern arts (Post 1882) can trace some of their ways of thought, thinking, and most importantly, movement to Judo.
5. Budo is for war. Judo competition is war.
6. Zen Judo is something else, but it is not Judo.
7. BJJ has Judo Roots. BJJ and traditional Japensese JJ are nothing alike.
8. BJJ's arsenal is vast, but lacks the options of Judo IMO
9. Judo is niether better, nor worse then any othe art. It all depens on teacher, situation, and what you're in it for.
10. Judo is fundemtanlly diffrent, yet very much the same as all arts.
You can read a very good account of how KODOKAN Judo came about

P.S. I'm an elitist Judo Jock, does it show? :rofl:
