It seems plain to me sir that the difference is, Heretic can see his posts and therefore he is not talking behind Heretic's back. Or hadn't you considered that. I would contend that your objectivity is clouded by your negative emotions. That is never a good thing. You should work on that.
1: CC can choose to see TH's posts if he wants. Nobody has forced him to put TH on ignore and if he's gonna go around inventing up garbage and bad mouthing a poster he supposedly has on ignore then neither he, nor you (either) have any sort of case, not that you had one anyway.
2: Neither you or you, sorry, CC have any basis for lecturing anyone about objectivity.
