Interesting that I agree with you except that I would occasionally want to admonish the odd Democrat here and there to stop behaving like a typical Republican. So it appears that we are aware of the same problem, more or less, except in mirror image. Still a step in the right direction I suppose.
On the rare occasions when partisanship has been put aside, I've found that conservatives and liberals actually believe in a number of things that are similar. There will be obvious issues where they are polar opposites, but we can get back to civil discourse and fixing things if we just focus on the items that we both agree on, and the problems with politicians in general, without every...single...issue... requiring an "enemy at the gates" response.
