1) Pinky,
Stop twisting our words! 
WHO said anything about children ruling over their parents? NOBODY EXCEPT YOU! Not once did we suggest that children should tell their parents what to do. How does letting your child believe what they want mean that they are suddenly ruling over you?
2) In answer to your question: It would work because everyboldy would believe what they wanted, and nobody would be being forced to believe something they didn't want to believe.
Now stop talking about totally irrelevant and ridiculous things and address the issue...
