Since you couldn't be bothered to post a link to back up your assertions Cuckoo, I had a quick look (on the basis that I wouldn't spend too much time looking for something which might not exist).
I found this in a NC document. Is this what you're referring to?
Every state-funded school must offer a curriculum which is balanced and broadly based* and which:
promotes the spiritual, moral, cultural, mental and physical development of pupils at the school and of society
Perhaps you would be so kind as to point me to the part of the document where it says whose morality should be imposed on the children when they are being taught about sexual matters.
