to everyone.
thanks for your replies…but, i still think that in general, KF is more refined than BJJ at it’s higher levels. - but, granted, there aren’t many that are able to reach those levels; probably myself included.
to say that you can really learn a system of KF in a few years, training like most of us do, today, in our ‘modern’ society; i think, is a greater fallacy, than thinking it takes 15-20 years to gain proficiency in an art. - it does, unless you train like they did in the old days. (then maybe you can cut the time drastically, to say 3-5 years. - but, realistically, very few of us have that luxury, of not needing a full time job to support ourselves.) - also, like i mentioned previously, you can train for 40 yrs and still suck eggs. - to get really good at KF takes an extraordinary effort.
i’ll agree that training in BJJ, you can get fairly proficient at it in a few years. - but the same goes for boxing, muay thai, JKD, etc. (not to say that you wouldn’t get better, the longer you practice.)
but if you think that somehow, that makes BJJ ‘superior’ - i’ll have to disagree. BJJ works good for UFC/NHB type events. but, in the street, rarely is a confrontation 1 on 1, and you just can’t afford to take a fight to the ground. (also, i always carry a blade on my person. can you afford to try and take me down then? - and don’t think that if i plan on using it, that you will know about it. - i understand the importance of ‘surprise’.)
in a fight, the last place that i would want to be is on the ground. - if i was trying to deal with one person, while rolling around on asphalt and broken glass, i would be foolish to assume that the person doesn’t have friends with him. and on the other side of the coin, if i were taken to the ground, there is a good chance that that is when my friend would come with a beer bottle to the guy’s head. - that is the “Reality” of the streets. - that’s why i think it is so funny that BJJ’ers think that KF guys are the ones not dealing with “Reality”.
-lets also take into account the types of people that certain arts draw. - certainly this is a generalization, but, people like to generalise about the types that take tai chi, so turnaround is fair play. 
BJJ IMO seems to attract big, muscle bound guys that are into ‘fighting’, and want to ‘fight’. - like they have something to prove. - i think KF gets lots of guys that are into many things besides fighting, such as personal development, health, the artistic aspect, etc. (hence the ‘juice bag’ look vs the ‘beer gut’ look. (more generalisations.))
but, lets say that someone decided to document one’s system for public dissemination; do you think that the gracies would incorporate that into their curriculum? - i doubt it. - they may train to fight against their tactics, but, that wouldn’t really change/“improve” the art. (e.g. they wouldn’t start practicing high kicks - as a poor example.)
lets take iron palm as another example. - certainly, any mixed martial artist can learn it, and it would be to great advantage in the ring. but first, they would have to acknowledge it’s effectiveness in their own minds, before they would come to the conclusion that it is worth training in. - now, who couldn’t use more powerful strikes as a fighter? - so why don’t they? - anyone can go buy brian gray’s books/videos or wing lam’s etc. etc.
now kung fu, also embraces philosophy, in many cases, and it is part and parcel of it… and a KF teacher may not teach a student iron palm, if they feel that they would go out and use it for ‘base’ purposes. (as it would bring ‘dishonor’ to the school.)
now, i am not saying that this is the case, but, perhaps a BJJ instructor won’t take something like this into account. - he’ll teach some guy, that will use the knowledge to go around picking fights. - but to reduce the possibility of that, many systems of KF used to put their students through a “test” phase to judge their character (sometimes for years).
how bad would it be if your local school bully was well versed in techniques meant to maim and kill? - that would suck. - e.g. i can show someone how to snap someones neck, and that requires very little skill or strength. - a person with little skill can do it against another of little skill. but, in a case of a regular HS school yard fight, wouldn’t it be better if neither knew how?
when you put out that kind of information for anyone to see, (just like you can learn how to make bombs off of the internet.) you can potentially ever now and again end up with situations like that of columbine HS. (i am perhaps giving an extreme example, but hopefully you get the idea.)
what about the issue of responsibility
