Evidence of what? I'm telling you they do randori. What you choose to imagine that means is your business. Who said anything about strikes or weapon use?
And I'm telling you that not all randori resembles Judo randori. Especially when you have a MA that is largely based on Kata like Tenshin Shinyo is. Further, my research on this Jujutsu doesn't mention randori at all, so some counter-evidence would be appreciated. If you have no evidence to back up what you said earlier, just say so.
No, that's your ignorant assessment, as someone with no knowledge of what classical Japanese jujutsu really is. By way of correction, you have had several active koryu jujutsu practitioners repeatedly tell you that you are both wrong and insulting with that description. But perhaps you're just too lacking in reading comprehension to understand that, so I'll spell out the distinction for you.
People who "dress up as knights or pikemen and playing around with medieval European weapons and participating in renaissance fairs" are by definition "playing around". These people are not practicing martial arts, and don't claim to be. They have no connection to the warfare or weapons they are "playing with" and in the example you describe, typically have little actual knowledge of medieval warfare outside of what they have read in books or manuscripts. HEMA is by definition reconstructed.
The koryu are martial arts with a direct connection to the time when they were actually used in war. They claim to be martial arts, teaching martial skills that have been obsolete for centuries. Trying to diminish or dismiss them by pointing out that they are obsolete is just weird.
Of course active Koryu practitioners would say I'm wrong, yet not provide anything to show that I'm wrong. They simply don't like how I characterized what they're doing. Sure, I'll grant that people who participate in classical Japanese Jujutsu probably have more direct connection to the actual obsolete martial arts of Japan than their European counterparts (mainly because European knights became obsolete centuries before the Samurai did), but does that make what they're doing any more applicable to the modern era? In the end, you're still playing dress up, practicing a martial art relic, and indulging in a culture that you don't belong to. Like I said, if you're Japanese, wishing to sustain your cultural heritage is understandable, and if your family were samurai, I understand it even more so. People want to preserve their cultural traditions for their future generations.
However, if you're some white dude from Europe or Australia attempting to preserve a culture you don't belong to.... well I suppose we all have our interests.
The fact that you seem to have a problem with other cultures dress differently is similarly weird and has nothing to do with anything. Using insulting characterisations as you have reflects poorly on you, not the arts or practitioners you immaturely attack. As I said before.
I have no idea how you got that impression from what I said.
If you think your opinions as stated above are 'truths' then I can see I'm wasting my time talking to you. Your inability to distinguish your own personal biases from objective reality is disheartening. But then "I should of known better" hey?
No personal biases here my friend, only observation. Since the fighting application of these classical JJ arts are pretty close to nil the only purpose for them is dressing up, learning some Japanese culture, and getting some sort of personal gratification for learning difficult pre-meiji choreography. Again, there's nothing wrong with that. The problem is that you don't want to be compared to a renaissance fair participant, despite the fact that you're not very different from one.
But hey, at least you look cooler.
