Never has our great nation been more bitterly divided. A question of desperate import hangs over us which we're barely beginning to address. Religious, political and economic differences are all just shades of grey, mere matters of emphasis, small print on society's contract, compared to this. There can be no compromise, no consensus. The battle lines are drawn and the final conflict will only end in the utter defiance and refutation of the values of one side or the other.
