Not XKan = Fake

Nuff said.
Even a poorly skilled shodan who goes off and starts his own ninjutsu school is more authentic than Ron Duncan will EVER be because at least the crap shodan's new art has sprung from something genuine even if it aint much good.
I don't care how gifted *certain* people think Duncan is a martial artist, and I am with those who believe he isn't, the fact is that you can't invent a new style of ninjutsu that has no links to any genuine Japanese Ryuha of that art.
I've used this analogy before but it would be as absurd as me, a British chap who has never been to America, starting my own Navajo Knife Fighting Method and paying no attention or seeking no guidance from a real expert in said methods.
Californian Maki rolls are just about the only acceptable American version of something Japanese and even they are based on genuine maki, rather than being made out of cheeze whizz and oreos, which is basically what Duncan's American Ninjutsu is.
