Except your own children are “other people.” They may not “be just fine.” Some religions are abusive and traumatizing. Why should adults have to deprogram themselves and recover from trauma later because their parents decided it was fine to indoctrinate their own kids? “Mind your own business” applies to parents too.
This is just useless gatekeeping. You don’t have to be a parent to have a perspective on how people should be raised. Every adult was a child at some point, so everyone has an experience to relate about how they were raised and the flaws they see in different approaches from their direct experience. Parents aren’t the only party involved. Not only does it take a village to raise kids, but other people are ultimately affected by parental decisions (e.g. Jennifer and James Crumbley).
