I like hearing about how other branches of wing chun learn and train their model or system. I find that stuff very interesting. My so called hostility is not about hearing how our models differ it is about many of the claims made about the models or training and it isn't hostility it is instead that I do not believe and question the claims made about the training. I know people who are focused on the model won't believe this but the model or system of wing chun ultimately doesn't matter at least if your goal is developing fighting skill. So why it is interesting to hear how the models or systems are different those differences don't really matter. This becomes as obvious as the nose on your face when you start seriously sparring. It's funny when people think their models are better than some one else's who can beat them silly.
I for one would not mind if Hendrik talked about his model of wing chun and the training he DOES. That would be interesting. When he talks about how his model is original and produces the best results and anyone not doing things his way is not doing wing chun and he's not even doing it then it calls for derision in my opinion,
