I shall declare myself as an agnostic before commenting - that is to say, I do not know the answers to the big questions, and firmly believe that no-one else knows either; some people have beliefs, but, as my local vicar agrees, no-one knows.
First of all, I do take the point made in the article, that those atheists of an evangelical bent do not seem to ask the basic questions of their believer fellows on which to base their attacks. It might be better of they stuck to setting out the facts as they see them, if they do not feel ready to ask those questions.
However, I have posed the question to many believers as to what/who god is to them and all the answer are different - which bears out my own belief that god is a human construct - and that is not intended as a criticism.
I also think that the sort of sophisticated theism that is implied in the article is not necessarily the norm - we have only got to look at what is happening with the fundamentalist movement in America and the downtrodden and huge Catholic families in poor areas of S America and elsewhere to see that the "superhero" image of god is alive and well.
