I agree with you Horace. I reckon the warbow guys have figured how to draw the heavy bows and have demonstrated that often. The rolling loose is just some daft dance that kind of makes a regular loose look vaguely like something worth learning because it may give you an 'edge'.
I joined the warbow society as an associate, to see what it was about, I have to say I was not impressed. The forums on the website is dead and a few members just said it was because everyone uses facebook and I was told to use that as I was keen to discuss proper technique as I attempted to up my bow poundage with my own home made longbows. My experience of the society was that I was booted out of the face book group because they did not know me. To say I was cheesed off after only just joining and paying a £5 for the privilege left me bitter. Seems like a bunch of lads that just meet up once in a while to hero worship those blokes pulling big ass bows. Not really an open society to welcome new people and teach how to shoot proper and correct medieval form, more like an ego trip for people who think they know best.
Considering every shoot is heavily attended, by kids, wives, girlfriends, parents... All shooting various bow types and weights, your claim is a bit daft to say the least.
The fact that you got "kicked" out of the Facebook group was a result of one particularly childish moron trying to cause trouble on his little ego trip (he's still bobbing up everywhere interestingly enough, repeating his inane comments as if nobody knows it's him haha!) It did leave a few trust issues sadly, but in general it's pretty healthy, and there's been a lot of new members lately. As Mark told you, on the thread. Where you got his name wrong. Twice.
Turn up at a shoot, ask questions, be involved. Watch them using these techniques first hand. Or sit on a forum and complain about it. It makes no difference to anybody else, but bad mouthing a society you've never shot with isn't really the way to go, is it. Not very dignified.
Anyway, as Del said ages ago, it's an irritating conversation that goes round in circles because nobody is willing to change opinions on it. Let's try and avoid getting personal, and all agree to never bring it up again
