"A majority of so called agnostics and atheists in Europe are cultural conservative Christians without even knowing it. So what is the difference between cultural Christians and religious Christians? If you have a personal relationship with Jesus Christ and God then you are a religious Christian. Myself and many more like me do not necessarily have a personal relationship with Jesus Christ and God. We do however believe in Christianity as a cultural, social, identity and moral platform. This makes us Christian." Anders Breivik.
Or put another way - he ISN'T a Christian at all - and is streets away from being an evangelical or even fundamentalist! ( Ironically, much of this is not too far from the definition of what a LIBERAL christian is!)
