While you need to do what's best for your family and financial situation, I vote "no." This is how indoctrination begins, at young ages. While the world is filled with people who will challenge us on our views, and I'm not suggesting to shelter one's kids by any means, I wouldn't pay for a child to attend a school that teaches concepts that go totally against the fundamental beliefs of the family.
