The more that the Christian underpinnings of Western society are removed, the closer we move to that time when, as Thomas Hobbes wrote long ago, life will be "nasty, brutish, and short" once again, as it was before the advent of Christianity. The otherwise well meaning individuals who shuck Christian theology in favor of a supposedly more enlightened secularism and/or Eastern religious belief don't seem to have a firm grasp of the fact that Western culture is like a house of cards, and when you remove the card at the bottom of the house, which is Christian theology, everything else falls. Christianity's twin beliefs that each and every human being is created in the image of God and that God became man to restore that image lie at the very heart, center, and foundation of Western culture as we know it. Without this theology, human beings have no inherent value. This "dangerous idea" of Christianity stands as a direct counterpoint to the pre-Christian world it conquered, and to the pre-Christian world that still dominates many places. Trash it at your own risk.
