After having seen many threads and general comments on martial arts and ninjutsu related topics around the Internet, I noticed many people accuse today's ninjutsu being either unauthentic and/or a false martial art, be it bujinkan, genbukan or jinnenkan. This has bothered me much because in the short time I've been studying, I've found it to be very beneficial both mentally and physically, not to mention effective from a fighting perspective. Correct me if I'm wrong, but aren't martial arts supposed to adapt to the society it is being taught in? Although the wars of today are not any less common, they are being fought primarily by drones, jets, missiles and guns. Sure there are many troops fighting but if you live in the West, you don't live in a battle zone. No matter how poverty-stricken your neighborhood may be, you don't have to worry about rampaging Mongols bringing your wall down at any moment while you're sitting on your living room couch watching TV. Times have changed. So then, could it not be said that the effectiveness of modern day martial arts would naturally be toned down to accommodate for the heavier influence of laws? In regard to specifically ninjutsu now, why would a modern school stress practice of assassination (not to say you shouldn't know it at all for the sake of tradition and knowledge)? If something like that even needed to be done, you'd have to join the military, learn their techniques, and then by order of the government only, you may or may not need to perpetrate that order. You can't just learn assassination in a dojo and go assassinate someone, not in a land of laws. This thread may seem like a rant but I'd actually like some discussion on it. As long as it benefits you, it's good, right?
