I'm responding mostly to NB's criticism of KF guys who don't get in the ring. I respect NB's journey and abilities and I don't necessarily disagree with him, I just don't see a need to criticize those who aren't interested in fighting for trophies.
I just think he'd be better off showing what he does and can do instead of worrying about the form collectors, because as it is we have forums like Bullshido that already do that.
Not to mention I know people who do taiji because they are dealing with cancer, old age, repetitive stress injuries, car accidents or any number of things and I don't think their goals are any less valid.
I've done a fair amount of bjj/judo and boxing and I have no doubt that it's not for everyone.
