This question actually came up some time back, when I was in a bookstore (yes, at one time stores actually sold books ). Anyways I was reading this book about being a teenage Wiccan. It had some clever arguments that you can use, should your parents protest.
Clearly we are not living in the same country we once were 60, 50 or even 40 years ago. Religion has lost its power. Sorry, but it’s true. And most parents are pretty open-minded.
But what if your parents aren’t open-minded? Take the following hypothetical example. Say that your parents are atheists. And they brought you up as an atheist. Then suddenly (use your imagination) the child finds themself in a fundamentalist Christian household. How much power does the new family have to change the child’s beliefs? And what reasonable measures can they use? ‘Go to your room! You’re grounded until you accept Jesus Christ as your Lord and Savior!’
Would that work? And what if it doesn’t work? What if it can’t?
And just now I was thinking. The situation can work in reverse. What if a Christian child suddenly finds himself thrust into an atheist household? You get the picture.
EDIT: And I was just going to add, the US Bill of Rights doesn’t apply to private conduct (‘Congress shall make no law…’). But I read in a good source (possibly a text book), that sometimes the government’s and the private sector’s interests can overlap. And of course private law does sometimes offer some (private sector) protections that the US Constitution doesn’t.
