I do think that there is a fundamental divide between people who think that atheists and theists have a common goal, a goal of understanding one another better, and those who think that the only legitimate goal is the partisan goal of advancing one's own viewpoints. I think that is the dividing line between people like Loftus and people like Lowder.
What is likely going to be the result of the polarization of the question of religion is that even with the enhanced communication provided by the Internet, we are still moving toward a culture in which we communicate seriously only with like-minded people. When C. S. Lewis became the first President of the Oxford Socratic Club he talked about the value of such a debating society for the community of Oxford University. I have often wondered what a certain well-known Oxford atheist would have done had the Oxford Socratic Club were still in existence, and he were to receive an invitation to present a paper and engage in dialogue with the resident Christians (such as C. S. Lewis).
Since I'm a theist and a Christian, I like to see people become theists and Christians. But I also like to make sure there is an open community of discussion concerning these issues, something I value independently of it as an instrument for getting people to agree with me.
