Separation of Church and State

The separation of Church and State has always been based on a lot of superstitious hogwash. Why should stupid religion always in cahoots with stupid politics have to pretend that they are separated? The existence of the State should be above the Church. In fact, in this 21st century, the church should already be dead and buried and gone. The Church knows nothing of the secret of life after death. She knows nothing of the secret of life after birth? So what exactly does the Church know since even her own God continue to remain nothing but an useless mystery? Poch Suzara
