You know, I was going to leave this, and heed MJS's very sage advice. But if you're going to return with this, then I'll add and clarify, as I'm sure the OP is not around to be upset by their thread being disrupted. That said, this is it, okay?
I didn't want to bring up your history earlier, or I would have linked to your earlier threads for the perusal of the audience. But to briefly recap, you have no experience in Ninjutsu (which is fine), but you continue to use the term (incorrectly), combined with your childish gibberish language (Kug Maky Ung), as well as terms that have very specific religious overtones (Shugen), with no attempt to understand, learn, or demonstrate any real interest or respect for whatsoever. You have been corrected many times over such things, and been guided towards legitimate schools (you even spoke at one point about attending a seminar held by Brian R. Van Cise, although not in Bujinkan/Ninjutsu, and made no mention of learning that art from him), only to have you complain that we are reacting from "fear". We're not. Get that idea out of your head.
I personally have no real animosity towards you, and certainly have no motivation from "fear" or any form of "self loathing". You may be projecting a fair bit there. What I do have where you are concerned is a lack of respect, as you have a complete lack of respect for the art you are trying to use the name of, as evidenced by you never really making any effort to learn from what you were being told by people who have been training and studying this art for decades. If you want to come back to the Ninjutsu forum and ask realistic intelligent questions, or even simple dumb ones, and are willing to take the answers on board, then great. But based on your posting here, and your continued use of your made-up base-less art using the name "ninjitsu", I don't see that happening.
As far as the group letting you join in, I sincerely hope not. If you come across in person anywhere near the way you do here, you wouldn't be allowed in my school, that's for sure. And if the person taking the class had seen any of your earlier threads, I'd suspect that they may take a similar tact. As said, it is a private dojo, which means they will be rather selective as to who they allow to train there or not. It's nothing to do with your background, but in your approach to these arts, which has been less than ideal to say the least.
Now, Emilio, you may have been offended by my refering to you as "son", but that was done for a very good reason. You continue to live in a fantasy land of your childhood imaginings. So, no matter your chronological age, you will be thought of as behaving like a child (in fact, this thread is no different).
Oh, and just to demonstrate that your understanding of such things is incredibly limited, you really have no idea what the "higher levels" and "esoteric training" of Ninjutsu are, or what the results are supposed to be. You said that I have "shown my true spirit", well, good! But you seem to misunderstand things quite badly again there. If we are talking martial arts, then a martial artists spirit should be one that does not hesitate to cut down things which should not be there, to excise aspects that are destructive, and to not hesitate to act in defence of their ideals. Which is what I did, and am doing. So you missed the boat on that one, I'm afraid....
If you want to understand the Ninjutsu traditions, then I will be here to answer any and all legitimate questions you have. But you will need to demonstrate that you are genuine, as there has never been the slightest indication of that in the past, and continues to be absent now.
