It’s possible. The wording of anti-predatory child protection laws already identifies negative religious conditioning in all but name. Physical, psychological, and intellectual abuse are all singled out in the U.S.’s 1974 Child Abuse Prevention and Treatment Act (CAPTA), Australia’s Children and Young Persons (Care and Protection) Act, and the UK’s 1989 Children Act, to name just three. Broader still, the central articles of the U.N.’s 1989 Convention on the Rights of the Child – the right to survival, the right to develop to the fullest, and protection from harmful influences – could clearly be used as grounds for such a move. This would mean no more tacitly proselytised Muslims or baptised-without-consent Christians. No forced First Holy Communions, no Bar Mitzvah’s, no Adhan prayers, no Aqeeqah, no Ceremony of the Sacred Thread, no Chudakarana,and no circumcision. There would be no religious coaching, no predation through organisations like the Good News Clubs and the Child Evangelism Fellowship, and no Sunday school… all of it replaced – perhaps, if at all – with comparative religion studies in the last year of school.
Making the case would not be at all difficult. Consider the massive, long-term intellectual abuse wrought by anti-science Creationist nonsense. Think of the enormous psychological torment sown in children who’re told from the youngest possible age that they’re fundamentally flawed. Fathom the terror seeded in a child’s fragile mind when fed nothing but the perverted threats of Hell; a place of eternal pain, constructed, so they’re told, specifically for them by their own loving god just in case they don’t love him back quite enough, or in the right ways. Think on the horrors felt by a child led to believe they’re being stalked day and night by a vicious hobgoblin. Reflect on the generations ruined by sexual abuse and church sanctioned child rape. Think on the very horrors of convincing a child that some vile extraterrestrial alien force will one day, perhaps today, lay waste to the entire planet, incinerating everything they’ve known and loved. Consider the far, far too many Margaret Schlosser’s, 10 months old, whose mother, Dena, cut off her arms while listening to church hymns as “an offering” to god before the apocalypse, or the many, many Faith Lovemore’s, 6 weeks old, who was butchered by her mother, Julia, by having pages of the bible shoved down her throat because her mother wanted her to ‘absorb’ the books message of love. Let the auditor tally the one-hundred and seventy-two (known) cases of Christian parents in the US murdering their children by denying them healthcare in just the last 20 years, and the thousands of children who have been tortured (sometimes to death) at the hands of their Christian parents using Michael and Debi Pearl’s Christian parenting manual, “To Train Up a Child,” which identifies discipline techniques such as, Inflicting punishment until a child is without breath to complain, Using plastic plumbing tubing to beat children, and Training children with pain before they even disobey in order to teach total obedience. And let this survey of all things monstrous score the Christian Dominionists who insist children should be stoned to death in public squares should they break Religious laws laid out by illiterates who couldn’t understand clouds, let alone thunder.
Would, however, outlawing religious indoctrination of children be discrimination? Of course it would, in exactly the same way enlightened societies presently discriminate against alcohol, tobacco, firearms, and pornography when it comes to minors. Given it is therefore possible, even reasonable, if not necessary, would Yahwehists feel their religion could survive in any coherent form past even a single generation if their stock of fresh, unguarded, hopeless, naïve, questionless meat was cut off? Could any Yahwehist chapter survive past a single generation if the decision of whether to choose a religion or not, and which one, was reserved until after a child had reached an age in-line with a countries voting/drinking laws wherefrom they could make an informed decision on their own? How confident would theists be for the longevity of their particular religion if joining that religion was left to young adults to review the tangled nonsense produced by Christian (and other religious) philosophers and make a decision based on evidence and rational appraisal, rather than indoctrination and fear based on superstition and magic?
Indeed, given the strength of the case that can be made for such a ban, is this even something Yahwehists would do willingly for the general good of children everywhere? Would any theist feel confident enough in the solidness and rigidity of their faith to trust mature, educated people to review that faith with a critical, honest, adult eye? If the theists answer to this question is No, then they have already more than answered the title question.
