Not surprisingly, I'm going to disagree.
If such conversations are advancing ideas that truly have no merit, then I believe the best thing to do is let those conversations happen in the open, where others can at least learn from it. Banning certain subjects, when those subjects are relevant to traditional hunting and tuning (whether you personally agree with them or not), helps no one learn anything.
I also don't see such conversations being driven by folks who are "crossing over from compound hunting," at all, or by folks who are seeking to have gear replace skill. And they are certainly not discussions that are the result of inexperience, looking at some of those individuals who are contributing to them. Nor do I truly find such discussions to be all that "techie" - no more so than discussions about the virtues of different string materials, etc.
Maybe you are someone who has gravitated to traditional archery because you don't want to focus on technical matters. That's perfectly fine - I also appreciate the simplicity of it, and it is one of the things that has drawn me to it. But there are also many of us - dedicated traditional archers as well, who still want to be able to discuss such matters, and learn from the experiences of others. This always has been a fundamental part of our "tradition." I see nothing wrong with this, and certainly nothing so extreme that it should be "banned." There will always be threads that interest some more than others, no matter what the subject, but all of these subjects are still relevant to the topic at hand. If a certain topic doesn't interest you, it's simple - ignore it.
The idea of a "Tech" forum could be a constructive solution.
Again - I believe the most valuable learning happens in the open, not by shutting doors. And that all of us, regardless of experience level, should hopefully still be open to learning. "Tradition" only avoids stagnation by being balanced with an open mind.
