I will give you my opinion on the topic -I myself see nothing wrong EVEN if as you argue the child was 'forced' to to this... I myself have forced my children to do many things brush teeth, do homework, go to bed, come inside...
Really -force is not the issue -the issue is the intent and the direction that some find potentially disgusting... Some might say that forcing a child to follow the teachings of Christ is a parents perogative and choice... Some such as myself see nothing wrong with EVEN the worst case scenario you moral relatively argue in ACLUish fashion...
Any person who objects to parents urging their children to do the right thing is at best a troll, wanting to disrupt this thread. Or he/she is a sociopath.
