Where are the common manners?

In recent years, I've had many off-the-cuff conversations with friends bemoaning the lack of manners in our society. Bitch, bitch, bitch. Laugh a little. Move on with life.

But it's a real angst-inducing societal issue, I fear. (I know...late the the panic session, but what the hell.) The recent election was another example of just how far out of kilter we've skewed. The hatred and vitrol being spewed by both sides - and I'm talking the voters. My god! I don't think I've ever been challenged to rationalize my beliefs so ardently and forcefully before in my life. Whatever happened to calm, polite disagreement? Concerted, honorable argument? Certainly, tell me why you feel the way you do. Try to convince me that I may be wrong, misguided. But respect me for my beliefs once I've listened with sincere ear. I promise to do the same. Let's disagree if we must, but save me the sneer as I turn to leave.
