Thanks Percy.
I know the current discussion is on-topic -- I explicitly defined how it was related to the subject, in fact.
I appreciate your efforts in trying to focus Dawn on one point at a time, but the simple problem is that Dawn won't do it. I don't know whether the avoidance is caused by misunderstanding of what is being asked or refusal to explain properly for whatever reason, but the outcome is the same: stalling of the thread.
I'm not sure whether direct moderation will really help, now that I think of it. That could only entail closing for off-topicness, suspending Dawn, or forcing us to cease discussing that issue some other way. None of those would help figure out what Dawn meant and the topic would be a vital one in any serious discussion of why ID is or is not science.
Perhaps a better method would be explaining to Dawn exactly what our issues are in a less hostile environment? Maybe you could try PMing him, Percy; that way the thread won't get more confused, and when the discussion restarts it will be on more level grounds where everybody is defining and using words or terms the same way.
