Just finished reading Johann Hari's interview with the former left-winger turned neocon supporter Christopher Hitchens. And some of the responses. It really got me thinking about the left, the right, and just about anyone else's moral clarity and logical consistency. After all, we all do it - we excuse/overlook the misdeeds of those we support while taking our opponents to task for their past actions. Yet while no one is 100% good, we are willing to overlook one side and not the other.

So do we strive for consistency - and end up with ideological purity, or do we try to be reasonable and end up with moral relativity?
