I have a whole host of matches over the past three seasons to "qualify" me as someone who can tactically out think others.
That's exactly the problem. You can't equate club tactics and strategies to the NT. They are very different. If you had helped out with the decisions in the past you would recognize that.
As far as the unwillingness to contribute in a public setting... that's absurd. You can't reinvent the wheel. The discussions are about very specific situations and would in no way translate into someone knowing how you would behave with you own club with different players and a different level of play.
