I agree with you Stephen, to at least some extent. But there are some realities:
1) This is Jun's house
2) I believe (and I'm sure he'll correct me if I'm wrong) he desires to cast a wide net...allowing space for the whole aikido community.
3) Sometimes our discussions cause some friction with established elements in that community.
4) Thus his idea of a seperate section.
5) Refer to number 1
So...if some of us wish a home to discuss some of these elements without the proselytizing, backbiting, nay saying, etc.etc...
It's up to us to create it, or find appropriate places for it. Nothing wrong with that. Just the way it is.
Personally, I think Jun hosts a fantastic site, and is EXTREMELY tolerent. I'd have kicked my butt off years ago.
