Collectivist ideology sees people as essentially interchangeable; they do not accept the idea that a child’s life is more precious than an adult’s. The Western leftist tradition also sees all people as victims and criminality as an expression not of moral weakness or lack of character, but of frustration and lack of opportunity. Canada, with its much beloved welfare state and universal health care, still wasn’t doing enough for poor Katrina Effert and that’s why she killed her son. It has nothing to do with selfishness, immorality, or evil.
For the left, “income inequality” causes crime and the criminal is actually a victim of an unfair and unjust system created by the only true evil in the world: Western civilization. More than 5,000 years of philosophy and moral tradition has led to the West being (until recently) the light in a benighted world. In a little less than 200 years, Karl Marx and his spiritual heirs have overturned those traditions and now we are a people who slap the wrists of child murderers while supposedly grieving for them. Now we blame the newborn for his murder by insinuating that his birth was such an ordeal it literally drove the mother mad.
About eight years ago I took a class in Meso-American art with an archeologist who had two decades in the field under his belt. One of the things I learned was that in some of those famous pyramid temples each corner had a sacrificed infant placed under the foundation. The first Europeans to come into contact with the Aztecs were rightly disgusted by people who killed their own children in religious ceremonies. Now their descendants suspend the sentences of child killers who didn’t want to get in trouble with their parents.
