Textbook selection in Texas like all states is dictated by the elected school board representatives. I am the first to scream foul at some of their antics however, they were elected by their people Nuff said. Most everything you cited is based on social conduct of accepted behavior which just happens to go hand in hand with most religious teaching. I suppose in some cultures it is ok to steal but for a society to succeed it needs moral values of some kind or chaos occurs. Laws are based to preserve order. The Sunday "blue laws' were rule unconstitutional a long time ago.

In other countries sure, but take away their religion and you still have the thuds doing what they do .. your argument doesn't hold.
