I came here during a research on a different topic. I am 44 years old, have survived the cold of one winter sleeping on asphalt (as a bum in our supposedly criminal scene), and was a small-scale criminal for around 3 or 4 decades of my lifespan. I stopped, when love and duty became better values to me.
People like Marc ‘Animal’ McYoung, Tony Blauer and so forth, are by now OLD. They are off the streets, where the real crimes and the real killings happen. They have the ambition to sell their ‘convenient solutions’, which does tweak their own judgment a little bit (proven by science).
One reason no martial arts will be a guarantee in self-defense is that it cannot block, dodge, or parry any form of poison or disease. Half the people disagreeing are homosexuals who are just too ill-informed to understand that their narcissistic need for attention is legitimate, but as well a progressing mental illness getting dangerous to themselves and others.
The other is immature and ignorant people needing to reinforce their own delusions and prejudices. A human factor, for those who shun the work to really discipline and develop themselves WILL always need excuses and postures.
My main reason for hating the fakes & frauds on certain topics is that they know they are sending people towards certain death, dire mutilation, and costly abuse.
I agree with attempts alike: http://www.samharris.org/blog/item/the-truth-about-violence/
Still that does not make me an expert on street-survival, crime-prevention, or martial arts. And my own most respected teacher was Dieter Knüttel, by now Grandmaster and ‘Bundestrainer’ of Modern Arnis, an armed filipino martial art. I prefer Muay Thai based stuff though. My best MMA teacher so far was a wanted murderer from Poland, who was among the bunch of bums I had to survive with. He was half my weight and nearly crushed my spine with the ease of a ‘throwing technique’ applied properly. But he is imprisoned now.
The bad news is: I have no martial arts product to sell, so those who want to fall prey to me must purchase my poetry ebook or click ‘gift me a coffee’ on my pseudo-landing page.
A good martial artist will know how to save lives, and not just how to cripple and end them!
