Firstly, I'm taking no sides - I had strong atheist views when I was younger, but gradually changed my mind.
There are many threads on MN about this, especially annoyance by atheist parents about collective worship in schools, and I have been wondering if it's recent that people have felt so strongly about it. I find it hard to imagine buses in the 1980s and 90s saying "there probably is no God", or parents taking their children out of assembly, or people muttering and sneering in the back row when attending baptisms (under duress): if it happened I was blissfully ignorant.
Speaking for myself, I rebelled with my heart and soul when my parents suddenly dragged me to catholic church every Sunday when I was 9. I saw the whole thing as utter nonsense, and a waste of valuable weekend time. However, I gradually changed my mind as an adult, but went CofE rather than catholic. I took the view that you did not have to take a literal view of the Bible and the church's teachings; as a child I was very literal-minded. I also love the sense of community in church.
Does anyone think it is because a generation of young adults are remembering being forced to obediently sing hymns, hear prayers from their school days, had to learn "impossibilities" such as the great flood, and are now making sure their children won't have to do the same, now that they have the right to say something which they didn't as a child?
