I totally disagree . We ' ve known for over a century , now , about the programmability of children below the age of 10 or so . It ' s a pretty powerful window that can set a kid for life , or screw them up for life , alternately . While an adult has free expression and free speech rights , those have to be tempered with the knowledge that speaking to a child is not like speaking to another adult . Adults can be plenty gullible , but children take it to a whole other level . Either the process of indoctrination is bad , in and of itself , because the process itself seeks to usurp the person ' s free will by leveraging this window of programmability . or we play picky choosy about which beliefs are bad to indoctrinate and which are acceptable to indoctrinate . You can guess where I fall . Programming your child to hate or fear the other parent is just as noxious a programming to believe in some ridiculous cult .
