The fine folks at First Things have published an article of mine entitled, Conceding Good Faith. It's was fun to write, as it reflects on my time in D.C. among a group of hard-left, Peace Corps liberals (who happened to include my girlfriend - hence my inclusion).
The article touches upon the need, in most cases, for a mutual concession on good intentions in political debate. As Charles Krauthammer once observed:
To understand the workings of American politics, you have to understand this fundamental law: Conservatives think liberals are stupid. Liberals think conservatives are evil.
At most, Krauthammer doesn't go far enough (maybe he doesn't have any Peace Corps friends). I suggest a sort of truce - if liberals truly want an end to toxic, impoverished political discourse, they must allow that conservatives also seek good ends, but simply disagree as to the most effective means.
I would wager most RONLT (Readers of NLT) have experienced similar trials. I hope you'll RTWT.
