It wouldn't be the first time.
In counselling and in the care and feeding of rugrats, there is what I call, "hooking the adult." It sometimes does wonders to suggest to the child or 'client' that they try using their rational minds, if any.
I'm not so sure how much it helps a fight to take a side. I MAY help to invite people to think.
Of course, when they would rather fight, "my work here is done."
AND when I see a principle being made victim to a fight -- when somebody attack the true principle rather than, say, it's less than true application, I will tend to go for defending the principle.
I felt like whatever else was going on, that was confusing to me, one thing I 'knew' was the difference between the two propositions.
