The 2nd most worrisome aspect of their practice methods, are the follow-ups that they implement. These usually amount to fatally injuring the assailant. Though being a valid option, this should not be the main practice conclusion to every defensive situation.
I suppose if one only wants to be familiar with some (different?) ways to (fatally) incapacitate someone (and isn't concerned with the legal ramifications for having done so), then maybe that is all that they need to study. Not exactly something that you could consider to be an "Art" though.
I guess what disturbed me the most about this individual's post, was the (obvious) belief that what he was participating in was "realistic". He described (in great detail) the donning of the protective equipment, and about how much they learned (?) from clubbing upon one another.
He seemed to be oblivious to the fact that he couldn't describe what the uke's reactions/responses would be from any of those (supposedly) completed technique applications. The only (result?) explanation of/for the described practice, was in regards to how much protective gear they had to use (because of the level of force they utilized in their practice methods).
Having had a few "off-line" discussions with this individual, I'm aware of his (general) beliefs regarding martial arts (which is why I find his summation and evaluations so ridiculous). He and I have discussed Taika's ability to knock individuals unconscious with just a light strike, for which though he (kind of) accepted could occur (he brushed off the majority of "point" strikes as either suggestion and/or even being subliminal/group hypnosis).
From what I've been able to observe, and even to participate in, what's generally being called "Reality", is (more often) simply practiced aggression methods (with little, to no protective application).
