Theology asserts propositions that cannot be proven true; ideologues hold stoutly to a worldview despite being contradicted by what is generally accepted as reality. When ideology and theology couple, their offspring are not always bad but they are always blind. And there is the danger: voters and politicians alike, oblivious to the facts.
We seem to prefer a comfortable lie to the uncomfortable truth. We punish those who point out reality, and reward those who provide us with the comfort of illusion. Reality is fearsome .. but experience tells us that more fearsome yet is evading it.
We have to face the unpleasant as well as the affirmative side of the human story, including our own story as a nation, our own stories of our peoples. We have got to have the ugly facts in order to protect us from the official view of reality. Otherwise, we are squeezed empty and filled with what other people want us to think and feel and experience.
