Apparently, Dave says we're a Christian country here in the UK, and shouldn't be ashamed to say so. I struggle to know quite what to make of that; in fact, I find myself somewhat torn between Nietzsche and the Church of England - which is such an odd thing to say that I guess it needs some explaining.
On the C of E side, I can see the benefit to society of being grounded in an ethical framework, and I can see that the only viable framework within our culture is, for historical reasons, the Christian one. I know people who are personally atheists, but made sure to send their children to a CofE school, because they perceived the importance of the broad Christian tradition in shaping British culture and values. I think this is broadly what Dave is saying: that Britain has been historically shaped by Christianity, and that we're fools to completely turn our backs on this heritage. Sure, I think.
On the Nietzsche side, I think there is something fundamentally ridiculous about trying to maintain some sort of 'Christian ethos' in the absence of faith in the Christian message and a life of discipleship. Thus the crazed prophet himself: "They are rid of God, and now believe all the more firmly that they must cling to Christian morality. That is an English consistency... Christianity is a system, a whole view of things thought out together. By breaking one main concept of it, the faith in God, one breaks the whole..." Real Christian ethics is not a generic morality, but a life shaped by the gospel and the command of God. How can it be applied in a sphere where the gospel is not trusted and the command is not heard?
There must be a better way to shape the values of public life within a broadly pluralistic society, other than building them out of the corpse of Christendom.
