It's after two in the morning, but respectfully, there are an awful lot of 'respected' martial arts institutions out there that don't pressure test, are more interested in ranks and belts, practice dead drilling etc. Historical European Martial Arts, by essentially being an explorative enterprise, has had to face up to the same issues as other martial arts without being able to hide behind arguments from authority.
Now, the flip side of the coin is that many eastern Martial Arts have had hundreds of years of not being tested, or firmly rooted in martial practice, within which to become sportified, filled with bullshido, become forms of meditation, or what have you - for example I have a reference somewhere to a Judo master in the 1910s saying 'We really need to crosstrain with striking arts to avoid becoming a sport', much in the same way that, for example, Olympic fencing did. By returning to the documentary evidence, and examining it critically, Historical European Martial Arts are forced to grapple with lots of questions that could otherwise be swept under the rug of 'That's how it's always been done.'
As someone running a research group into HEMA, I'm afraid that I hold the opposite position to you. 'Think critically, rather than passively accepting' would be how I would phrase it, but essentially I believe that so long as you're not being disruptive to other people's ability to train, then you should be asking as many questions as occur to you in order to develop as a martial artist.
tl;dr, screw the Confucian approach to learning systematic approaches to inter-personal violence.
Edit for an added troll: Shōrin-ryū is a mixed martial art from the 30s. Bartitsu pre-dates it, which in turn is only narrowly pre-dated by modern Jujitsu. Equally, I can turn around and point out that last year I participated in a Cornish Wrestling competition, a recognised living tradition which dates back to at least the C16th, when it emerged as a regional style in existing European wrestling styles. Hell, therefore it has a living tradition back to time immemorial.
EDIT for an added talking-past-eachother:
If you didn't this is your cue to shut up with respect to making any more comments to me on your perceptions. Since, I have spent a lot more time than you at studying weapons and armor
I'll send you my thesis on historicizing the early documentary evidence of systematic approaches to violence from Western Europe, if it helps. Or the paper that I wrote on HEMA as a research endeavour and experimental archaeology - comparing the Towton massacre records to Shackley's look at 14th Century Japanese Swordsmanship (illustrated by the archaeological records from Zaimokuza).
Don't insult an audience that you don't know.
