What is Archbishop Rowan Williams on about? He knows much more about theology in general and about Islam than I can ever know, but -
1. There are so many varieties of Sharia Law, relating to branches of Islam and countries of origin. Even if it were feasible to have a different variety in each location in Britain it would still not take account of the multi-ethnic origins of Muslims in each location, such as Slough.
2. Could inhumane punishments and oppression of women be excluded?
3. He has provided a field day for out-and-out secularists who take separation of Church and State to mean that religious belief and practice should be restricted to the purely personal and have no bearing on politics or community life at all.
