You miss a key point in your numbered list of the various aspects of this situation: that ODP is supposed to be a cooperative effort, and that (editors name removed) and other editors at ODP ignored their responsibility to make some effort to cooperate with someone who obviously knew something about the subject matter, and who had obviously made a sincere effort to organize a directory that no one was managing.
Ummm, excuse me but did you make a cooperative effort to communicate your ideas before you decided to make changes that went against the guidelines? The path runs both ways. You get what you give. Apparently you gave no consideration to the guidelines or the hours other editors spent arranging and adding to that category. Why would you expect anything more than you were (are) willing to give?
