This isn’t child abuse and even comparing something like home schooling to child abuse is completely unnecessary. Lots of countries allow people to homeschool their children, which of course will include spiritual stuff the majority of people of today will not agree. Some cultures lie to their kids about Santa Claus and other shit and no one cares, because kids aren’t as stupid as we often assume. Kids can change their perspective easily once provided with new information - something that a lot of adults struggle with due to cognitive dissonance.
