Bradley Monton is an interesting philosopher, an atheist who is opposed to the witch-hunt against Intelligent Design.
I would put atheists in three categories. There are hostile atheists that make it their mission to smash religious belief. There are apathetic atheists who simple don't put a lot of effort into what they don't believe. And then there are sympathetic atheists who are willing to dialogue with Christians. Monton is clearly of the third type.
