That's all true - but we frequently pretend that it isn't. How often do we read or see someone push themselves forward as the Voice of Dispassionate Truth, when the reality they are as much a "true believer" as any other partisan?

How often to we entrust the role of Gatekeeper to someone only to discover they've been using their position to engage in insider trading?

As long as we allow people to put themselves forth as harbingers of Truth, nothing will change.
