Hmmm, can you quote some specific part of my post you feel as defensive? 

SpartanII, can you show any of these benefits are more than what the benefits that any low impact exercise that unites the physical part with a more psychological approach could give?

I never said there is no benefit in practicing martial arts, internal and external, thats not what my questions are about. Im talking about specifically the 'supernatural' claims that cannot be explained, like some supposed force moving through air and knocking someone out (where did this energy come from? violation of laws of thermodynamics, and if so, what can we learn from it?)

Oh and I dont understand what you said, I didnt join the discussion to say i dont believe, if you re-read what I say I made no claims about it for or against, im merely asking questions. If I wasnt interested i wouldnt be posting here in the first place.
