Welcome to Atheist Nexus. I'm living just a few miles from you, in Bradford-on-Avon, Wiltshire (also in Oxford). My strong views on the irrationality of religious belief are pretty well known. You can gain some idea of them by visiting the group that I founded in September 2008. It is called "Origins: Universe, Life, Humankind, Religion, etc....." Try joining one of the discussions. Cheers.
