When you post, you show someone How you wish to be treated; this cues them on how to practice the golden rule with you. Bruce apparently
likes to be abused by me, for he posts abusively to me with almost no dillution of content.

We cannot hide behind the forum rules as a reason not to post in good faith. What is good faith to you?

If you call someone a liar, that is not a personal attack if you have ample evidence
and they have truly worn through a deep layer of good faith attempts to reconcile. If one posts so-called evidence of that lying in a statistically deviant, misleading way, one might also be lying.
How deep is Yanniru's good faith? Can you point to your good faith attempts to reconcile that were not tainted by sarcasm, deceptive innuendos and lack of intent to follow through?
