This cultural secular education is a consequence of the environment of the society which typically includes exposure to other cultures with most citizens fluently speaking two or three languages, having TV and radio programs from other cultures, and having a strong public secular education system that includes studying comparative religions, world history, and world mythologies beginning in elementary school. Examples of such secular societies are The Netherlands and the Scandanavian countries. These countries actually practice complete separation of church and state even though their constitution does not separate church and state.
