I understand Fred...and truly, there is some legitimacy to your 'feeling'. What precipitates the polarization, though. Me, DT, Aragorn...I don't think so...it is those individuals that insist on strident propaganda to voice their opinions. An individual that has a true interest in dialogue will not lead with sarcasm, bitterness, ugliness, hatred, pomposity, etc. You get my drift. And we can't focus on those in the public sphere that represent the polarities...it is counter-productive. The hard truth is, when the center of a political position is represented by the likes of Rick Santorum, there is a major problem with that political philosophy.
