Pretty funny (but not surprising) that the thread on civility has become so un-civil.
If we can pause in the name calling for a moment, here is a possible explanation that relates to the original post: As you may have heard, last year the Republican members of the Texas legislature called three special legislative sessions to redraw the congressional lines. (You may have heard that the Democratic delegation fled the state twice.)
That brought up a lot of dicussion about who and how the lines are drawn. The point was made that a neutral/non-partisan body should draw the lines, because both parties, when in control, draw "safe" districts for themselves, which means that the person elected does not have to appeal at all the the center. If a district fairly is equally populated by members of both parties, neither candidate can be too "radical." But safe democratic seats are occupied more and more by very left wing politicans, and safe republican seats are occupied more and more by very right wing politicians...thus the rift between the congressional delegations has become huge instead of narrow.
I guess one of the reasons I respect McCain is that he is willing to disagree with his own party. Can you imagine having to support the "party line" on every single issue...foreign policy, defense, education, health care, the environment, farm subsidies, abortion...the list is endless, and I think most Americans agree with one party on some issues and the other party on other issues.
Take the issue of "life." As far as I can see, nuns seem to be totally and consistently pro-life: They are against abortion and against the death penalty. Democrats are largely pro-choice and anti-death penalty and Republicans tend to be the opposite.
