Iggi, I don't need to see how it is taught; I have two children studying RE in secondary school. I know the syllabus. The focus of RE is religious education; that is why it is called religious education. It is hardly controversial to say so.
Bunbaker, my children at different schools do two hours of RE a week and one hour of PSHE a week. PSHE has to cover every type of diversity (the other 4 main strands - race, disability, gender and sexual orientation) other than religion. There is no explanation from anyone on here as to why religious belief should get its own subject when every other element of legally protected human diversity does not. Race includes nationality and ethnic and cultural identity and origin, which is surely as important to know as religion, yet it doesn't have its own subject.
Other topics like politics, philosophy, sociology and anthropology do not have their own subject and also get crammed into PSHE along with all the other stuff PSHE has to cover like mental health, environmental responsibility, budgeting, drugs, alcohol and so on.
What is it about religion that makes it more important than disability, race, gender, sexual orientation, sociology (so the study of the whole of industrialised society), anthropology (so the study of cultures), philosophy or politics? Why are all these subjects attached on to PSHE, geography etc and yet RE has a whole subject to itself? Why is RE more important? Why can't it be attached on to geography, history, art etc where relevant?
