How can creationists be made better parents without jeopardizing all people’s freedom?

First of all, I just hope we’re all on the same wavelength here – creationism is bad, very bad and society is weakened because of it and it needs to be stopped. We could make laws dictating the type of things parents can and can’t tell their children and this would break the cycle of creationist lies, but I don’t think that will ever happen and even if it did, it kind of makes people lose their independence from their government. But what are some other ways that the cycle of creationist lies can be broken without people losing any of their freedom and personal liberty?
