Once core beliefs and absolute truths are abandoned on the alter of "tolerance", anything goes. Man becomes just like any other animal and all forms of behavior including sadism, pedophilia, beastiality, and perversions ad nauseum become acceptable and are normalized within a culture made up of depraved sociopaths.
Features of the physical world becomes dominant and replace faith, the soul, and moral absolutes as the foundation of Western civilization. Mother Earth "Gaia" becomes God, and man; no longer created in God's image, becomes the enemy of humanity and can be eradicated by the "enlightened" without moral, societal or legal repercussions. Entire societies and cultures can be exterminated for the "common good" in a world being exploited by the common enemies of mankind; man himself.
