PD,
I might point out that RE is not, of course, obligatory in the National Curriculum and it is down to each Local Authority to work out an Agreed Syllabus. In junior schools, where the children are generally so much more keen to learn such things, this works well enough. At the older level the need for a broader study of ethics, etc, is more appropriate; but to my way of thinking, it would be totally wrong to minimise RE, as it covers, not only the religious aspect of belief, etc, but broader issues which are encompassed in it. If older children, or their parents, are not happy with the time-table, or inclusion of RE in it, as I have pointed out, they are free to withdraw their child. But this does not seem to be happening.
