Even if you are neither a Jew nor a Christian, you are culturally ignorant if you know nothing of the Bible.
Which Bible would they use?
Well said. There is a side of me that has a problem with teaching religion in government schools, but I am torn. My children learned the Bible at home and Sunday school. There are times that I have allowed my children to go to Sunday school/vacation Bible school with friends of different traditions ... some traditions that I have problems. But my wife and I rather that they have first hand knowledge of those traditions. What I won't allow is my children to get first hand knowledge of Islam. They already get a dose of that at school, and I have to unlearn them by having them read the Koran and Hadith passages. In the process they get a good current events and history lessons.
I suppose I am torn because I do not trust liberal union thug teachers to do their job in teaching the Bible. They certainly do not do their job in teaching lessons about Islam. At least by teaching some things about the Bible it will provide less time to teach their queer, liberal, pro-Islamic agendas.
