"Religion plays no role in state-funded education, whether through religious affiliation, organised worship, religious instruction, pupil selection or employment discrimination."
This is not saying that children can not learn about religion, it is just saying that religion as an activity (i.e. group worship) is not a school activity but a personal one. You have definitely misinterpreted this completely. Like you say, how can you teach children about Star Wars, without understanding the bible story (for "Star Wars", you can also insert other great classics).
if they are both under attack --I think religious education is a higher priority to preserve than religious worship. - they are not and never were BOTH under attack, only religious worship.
You said: No, because I see no evidence that people of no religion are in fact being discriminated against because they have no religion. I do see evidence that church schools are being allowed to select pupils on the grounds that parents profess a faith.
Well surely selection of pupils based upon faith IS discrimination. I have a friend who's 5 year old will have to travel long distances to a school in another town, because the 3 non-faith schools are over subscribed and the remaining 10 schools are all faith schools that have selection criteria. How is this right or fair?
My own DC have to go to a non-selective CofE school and are told off for not praying in assembly. My own desires to allow my children to be exposed to faith so that they can learn for themselves means that they are not allow to express their own views (by sitting quietly and respectfully, but not praying), without being told off! How is this right? This is discrimination without any shadow of a doubt!
