I'm with you two. I know you won't realise this unless you look back on much earlier posts but this is standard Hanzou fare, we've had the same arguments for a few years now. The basic argument is that having trained karate he deems it pointless and kata useless, the proof of this is his karate training which as I have already quoted was at a McDojo ( not my words, his). BJJ is always the best, nothing else works. To be fair I've seen many martial artists of all ilks state their style is the best, it's nothing new. The 'video' proof is always demanded, like the joke, if it's not on video it didn't happen. The flaw of course is that the video is only proof of the individual's ability not proof of the style. I can post up videos of BJJ being practised in such a way you'd think it truly appalling.
I could post that CMA styles don't work because they don't work for me, I find them hard on my knees and after a lifetime of karate I find it very difficult to transition to their way of doing things, however I will not say they don't work because I know several very good practitioners who make it work a dream.
What is never accepted is that a style may suit and work very well for many people, it may well not work for you, that's fine, practice your style and not worry about other people's. 'Ah then' says Hanzou and his kind, 'We have to point out the inadequacies of other's styles otherwise you are being defrauded....
because we know best'. And that's the problem, if someone's work like Iain Abernethy's actually is effective ( and no he doesn't do the 'secret' technique stuff but has interesting articles which show how he thinks about things in depth
The problems with "street fighting" | Iain Abernethy ) for those who study with him and others like him, why does it offend those who don't do kata? You don't like it, don't do it. It makes no difference to you whether others do it and find it useful in it's many incarnations.
Still, arguing that ones' style is best is akin to arguing that one's religion is best or that having no faith is best ( one reason for not having religious arguments as well as political ones on here), we've seen where they lead. I like BJJ, I enjoy it, is it the best ever , no, what is? I have no idea but I do know that blowing other people's candles out doesn't make yours shine brighter. BJJ doesn't shine brighter because you think other styles are all pants.
