Great leaders in the martial arts community have always emphasized the idea that "we all win through collaboration and mutual support". A forum can be a rich and wonderful resource, but only if appreciation and respect prevail.
On my own part, I will continue to promote and teach the way my teachers taught me. If, for example, my Sifu/ Si Gung told me that he taught someone, I'm stating for the record that's what he said. If the next man's Sifu or Si Gung has told him differently, I encourage him to do the same.
Frankly, if we can't talk about lineages and differences, as forum members, we are left in a relative information vacuum. Therefore, I recommend exploring ways this can be done, short of insulting anyone (or taking insult), realizing there are those inclined to feign "insult", just to spoil a presentation, conversation or good debate.
Certainly, ban anybody who has shown a consistently disruptive agenda, such as the type likely to inhibit others from talking, or actually degrade the image of martial arts.
Best,
Michael Goodwin
