So, if it were up to you, specifically what are your concrete suggestions to ensure that parents don't tell children such religious lies", (your interpretation), who would do it and how, and who and how would it be enforced in any country?

It isn't my interpretation. It may be, on the other hand, a less than diplomatic way of putting it, but when children are being peddled myths as truth I don't feel like being diplomatic. If you tell children that this and that is in the Bible, and tell them that the Bible is very old and incomplete and not always even in agreement with itself, good. But if you tell them that the Bible is true, you're lying to them. If you tell them that many people think the Bible is true but some others ask questions, good. If you tell them that the Bible is the word of God, you're lying to them. If you tell them that a lot of people think the Bible is the word of God, but that other people have these doubts, good. As for solutions, that is not easy. I think that states should have nothing to do with religion. There should be no taxpayer-subsidised faith schools or similar institutions. There should be no "Church of England." There should be no religious leaders in public positions of influence, in the House of Lords for example. The BBC should not be broadcasting, at taxpayers' expense, religious broadcasts of any kind. Religion get a privileged, free ride all too often. That would be a good start. And very fair.
