The inspiration for this is the No Cross Talk rule from the f2f meetings of Alcoholics Anonymous. There you are not allowedd to say anything at all. Because this is not f2f we have to modify the rule some. People need to know that they have been heard. So affirm what you can. We allow this much in responding. But again, no questioning, no refuting, no alternate explanations, no attempts to change their thinking in any way.
