This is worth a half hour of your time. When we read horror stories about Nazi Germany or Stalinist Russia or the North Korea of today, we wonder how fellow human beings can treat each other with such brutality and contempt. The only way that is possible is for the people who are brutalized to first be dehumanized. Mass murder is virtually always preceded by a denial of the special status of humans, or some subset of humans, as created in the image of God. This denial is not limited to repressive regimes and governments. It is also alive and well – and equally dangerous – within the world-wide environmental movement.
As the narrator of this short documentary says, when human being are considered no better than animals, the result is not greater compassion for animals but less compassion for all living creatures- especially fellow human beings. Humans told they are animals eventually act as if they are animals.
