I'd encourage you to not make stark black-and-white statements about parenting, or judgements about parents who are doing it differently. I certainly wouldn't go about dismissing a parent's love for their child.

In this case, sure, there's almost certainly some children who should be left to develop their own ideals and values as part of maximizing their own potential and finding their own path. There are a whole lot more children who need to be taught some ideals and values, or they'll grow up to be an adult completely without them, and society will be poorer for it. Determining which group any particular child belongs to is the primary caregiver's job, not yours.
