Amazing how many experts here don't actually have a clue what is taught in schools and how religious lessons are delivered.
I taught religion education for 15 years and was head of department. I loved it and so did the kids because it wasn't the old, stuffy religious studies you remember at school but it is nowadays all about ethics, opinions, discussions. We are giving kids the tools to understand themselves and the world and male informed decisions based on the knowledge they have.
Religion studies is a framework for kids to explore the world, society and where they sit on topics that will affect them such as death, abortion, race, gender, stereotypes etc
At the very heart of religious education is allowing kids to form their own opinions and having the tools to express themselves. They are taught about different religions, societies, cultures which they can agree with, disagree with etc but they are doing it in an informed way.
If we go down the route of America or France where religious studies is not on the curriculum then you foster ignorance and intolerance. Look at the hate crimes in these countries. Pure ignorance and being scared of others fuels it.
The baying mob outside the school last week is a prime example of why we need religious education, I can guarantee of people who don't want freedom of speech I would guess they haven't had an all round education and show very little respect for views not of their own. Do we want to be a country that has zero understanding or appreciation of others?!
