This was a still-born thread more than two days ago, because it assumed that that the question it raised can be logically and reasonably answered.
After 179 useless responses, (sadly, many of my own) are there anybody still responding to this thread familiar with the term: "Beating a dead horse"?
It obviously wasn't stillborn because it has generated quite a bit of thoughtful and mostly respectful and civil discussion.
Most of those on the left are incapable of recognizing and focusing on a specific concept and discussing it separate from ideology, partisanship, and/or the politics of personal destruction. And of course consider it a 'non subject' when they are required to focus on the concept itself. I don't put you in those ranks, but if you do focus on the concept Paulitcian is getting at, the subject is actually quite fascinating. Nowhere near a dead horse.
