Here's the thing, I believe in my art, I wish I had the exuberance of my youth, with the experience of my years, I have offered to test my art against other martial artists, they have refused, as I am not a big enough fish, but the big fish do not want to risk their reps, I understand some of the arguments, but unless you have trained in Systema you don't know, you can say some things are not valid, or you can say it's no different from other arts in certain aspects, but until big fish are willing to step up, or people are willing to try it, or the art is allowed to show itself on the world stage, rumours and opinions are going to reign, I could spend 20 mins on the net and find substandard videos to ridicule any art on the planet, but I also understand Systema needs to prove itself on the same stage, all I can say is I am trying, if you try it and don't like it, fine, not your cup of tea, fine. Debate the art, I am up for that, it's healthy to debate, but to dismiss the art as parlour tricks, when you have not tried it, maybe that says more about yourself than your martial arts.
