If we look at what children have been exposed to during the course of time: e.g. child ritual sacrifice by e.g. the Incas, routine oblation of children to monasteries in the Middle Ages, tight swaddling to restrict the infant, severe child beating because of the common belief that a child was a container of evil and
therefore must kept down, daily enemas to verify that the child wasn't possessed, child labour and child slavery etc. -
authoritarian parenting can actually be seen as a step up the evolutionary ladder of child rearing.
