This quote only reveals a complete and utter lack of understanding of parenting and child development. I cannot imagine anyone who thinks this to be "beautiful" being a parent or a good one if they are. This quote, and the ideology behind it, are nothing less than disgusting.
The parent's job is to lay down a solid foundation onto which a person will be constructed. In some cases the parent is a filter. For example, the vast majority of Muslims are good people, no different from anyone else. Good parenting is what made these children immune to the pulls of derranged radical elements in that culture. Good parenting is what ensures the vast majority of those children cannot be swayed away from being good decent human beings.
That's just one example. Many more in history. There's a reason for which all cults try to get to children as early as possible. Parents are the only line of defense.
No, that quote is disgusting.
