What about Muslim countries with their State religion and sharia law which are theocracies, is that right for them or is it an exception too.
Why should Britain have to make changes to accommodate atheists et al. No one is forced to be Anglican or believe in any religion and neither is Britain a theocracy so no one loses out, it's all part of their history based on the Magna Carta really.
John, by the grace of God King of England, Lord of Ireland, Duke of Normandy and Aquitaine, and Count of Anjou, to his archbishops, bishops, abbots, earls, barons, justices, foresters, sheriffs, stewards, servants, and to all his officials and loyal subjects, greeting.
Know that before God, for the health of our soul and those of our ancestors and heirs, to the honour of God, the exaltation of the holy Church, and the better ordering of our kingdom etc. etc. .
