I'm not responding to the rest of this - it seems appropriate, but not something you need my reply on. I just wanted to talk about demonstrations not including beginners. I've done some demos where we basically did a class in front of people, with whomever showed up from the school, including folks with only a few months of training. Unfortunately, it looks like crap compared to the fight scenes from the movies. Given my 'druthers, I'd always do demos by just holding a class (using a class plan designed to show what people can do), but I've heard audience members mock when a knife defense fails because the knife attack is....well, a knife attack, and those things are dangerous, if the person means to hurt you. Often, people watching a demo (or demo video) want to see how good the art can be, and measure it against the fantasy world.You know what, I've read through this post 10 times and I really don't know how to reply to it, it's that stupid. But since you were clearly trying to provoke a reaction, I will try to oblige (even though it's probably not worth my time). First off, I don't learn White Crane (my primary art) purely for self-defence, but for fitness, socialising, learning the culture and fun. If I do learn some self-defence skills along the way, that's a bonus for me. This is fine because that is exactly the same focus as my instructor, which is why he is teaching a traditional Chinese Martial Arts system rather than a more modern self-defence system. It's also why we do traditional forms, weapons and archery as well as learning self-defence. That is what I signed up for and that is what I got.
On the other hand the system in the OP labels itself as a "self-defence system", in other words, teaching self-defence is its primary goal. If it doesn't teach it effectively then one would question why you would choose it over other systems? The video is a marketing tool, to prove that the teacher is skilled, knowledgeable and most importantly that the system works. All I said was that if you wanted to prove a system's effectiveness you would show-case some novices doing the techniques as well as the instructor. Yes of course the novices won't be nearly as fast or skilled as the instructor, but they don't need to be. If someone is looking for effective self-defence they aren't going to want to choose a system that takes 20+ years of solid training in before you can use the system in a live situation. One of the reasons why bjj is so popular for self-defence is because even after just 6 months of training you are probably able to use some of the basic techniques on a resisting opponent. Can you say the same for this system?
Finally (and I'm not even sure why I need to ask this at all) what does my choice of Martial Art have anything at all to do with critiquing a self-defence system?
