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.
My comment was not a blanket generalization the word "Most..." tells.
I do not imply that one should leave the child without values but that one should let the child pick up these values in a more natural, guided learning, not in a coerced acceptance of unwritten standards.
Let the parents be present to guide them in picking up the right values without forcing anything on them. Let them know the reason why something is more acceptable; don't tell them it's just acceptable and must be followed.
It's pretty clear that the groups being referred to are children who can be left to develop themselves and children who need more guidance, as outlined in the beginning of that paragraph.
