I am very open to discussion and to having my mind changed. Maybe you didn't have a convincing argument? Your arguments are always welcome and I will always consider them honestly.
Cant have a discussion without discussing things. You are not discussing but asking to be convinced when your mind is already set.
Saying things like "my system is the only coherent system" is not an open discussion, it is a statement that you will not allow to be questioned. Quite frankly the reason is if you allow yourself to discuss such a statement openly the outcome would be that you had to admit training an inferior system.
Problem is that this is not how we others view the world, in our view if we discuss techniques or theories then we may use other people's views to gather another insight in how people think and react to force or situations.... how other people may fight. Since you are so caught up in what is the one true system you fail to see that it is never the system but the fighter it is about. Even in your system everyone will come out differently with a different set of skills. Some because it was not the right system for them, others because they did not dedicate enough time to it.
Problem is that even you or some other student of your sifu will pass on this system and when they do, some parts of training will have changed. The way the system is interpreted will be changed over time. Memories fade, ideas shift. Understanding differs. Body changes. Your limbs grow weaker or you become more stiff with time. Eventually your system is not what it was because what it was will no longer suite you.
So you see, your point of view is not the same as mine and many others. Because you want to be convinced something is better or not, you are already there missing the full picture. Truth is that nothing is better or worse, just different.
Nothing is true or false, just a mix of both. Nothing is the true WC/VT, just an evolution over time and people/sifus as well as generations.
(And yes there are systems that are pure fantasies, we all know at least some. But they are not part of discussion regarding WC lineages)
