Yeah, you're pretty dogmatic about this when you decide you don't like a style. Pretty sure you wouldn't think it was so vague as to be meaningless if someone from a style you liked mentioned using a heavy bag.It just depends if you want to treat martial arts as a science or a belief system.
I am sure no touch guys can support their method with more method. I am sure there are books of explanation out there.
What they can't do is get a random person and make that method work.
See, all we've talked about in this lampoon of a side thread is what is done in training, not the effectiveness of it. You're essentially said that anything I say about how I train becomes a claim you feel no need to accept, even if it's a totally normal kind of training. You've also gone so far as to say even mentioning things like a heavy bag is meaningless in discussion with you, because it is too vague.
TL, DR: No sense talking to you about anyting, because it's all too vague for you to comprehend.
