IMHO, no religion in public school should mean just that - no religion in public school. If you start teaching any religion under the guise of history, then any religion should be allowed into the schools. :shrug:
So, again, IMHO, since LaPlata is teaching Islam, all local religions should be allowed into that school and taught. Or La Plata should stop teaching religion. They are violating the law. I'd sue. Actually, I want to sue right now, and I have no kids in that school. It's the principle of the matter. Any lawyers on the board who can tell me if I can sue without kids in that school?
You want your kids to learn religion - you send them to a private religious school, teach them your religion at home, and send them to attend church, mosque, temple, whatever.
If you are a teacher and want to teach religion, then go to work at a private religious school or teach att he church, mosque, temple, whatever. But by law, you aren't supposed to be teaching ANY religion at a public school.
