Words of wisdom...
Although if you introduce a subject in a discussion, be prepared that it may be addressed one way or another
@Guard Dog: I think it's a grey area, but one thing I would consider is whether or not the teachings of the parents are unconstitutional or not.
E.g. would you sit by the sideline when people teach their children that midgets and miniature people are not real humans and are only good for dwarf tossing competitions?
What about homes where kids are tought that people with skin colour xyz is trash and should be run over whenever you see them?
Homes where kids are tought that people who either have or don't have a certain faith should be burnt at the stake. Preferably at night because the "misguided" authorities are compromised by the "enemy"?
What if the parents put their kids in training camps in the desert of Nevada, where they learn to become suicide bombers, so they can blow up government buildings once the parents tell them it is time to fight the system?
I can sort of understand why it must be frustrating for those watching by the sideline.
You know, the U.S. has come a very long way since the 60's. A lot of racial barriers have been broken down. Did we manage it by taking away people's kids and telling them they weren't allowed to believe what they believed? No. We managed to make a difference by punishing real acts of cruelty, and enforcing integration so that the kids that were growing up would be directly exposed to those their parents told them to "hate". And that is the way you change society - slowly, one generation at a time.
There will always be those that hold on to their whackjob ideals, and try to teach their children the same, but if the government steps in directly, all that will happen is that those whackjob views will be reinforced as true. It is much more likely that a child will realize that their parents are crazy if you leave them to experience the world on their own. I mean, really, don't we all think our parents are crazy? I know my kids think I am!
