Btw, there is another line of thought going thru this thread, of which ed's post is an example.

"Some folks have hair triggers, and respond agressively and inappropriately to what they see as disrespect (valid or not)."

That is the thought about rancour and quarreling and pure personality clash.

It is an aspect of the discussion that I, for one, am not interested in for the purposes of this thread.

I have my hands full digesting the answrs which address the thread header directly.
