One of the bigger issues I have with Atheism+ is its seems to create political divisiveness where none is needed and could be detrimental. Atheists, by their nature, are going to be secularists, but not all secularists are going to be atheists. So, why alienate a group of people that could potentially be a political ally, especially since much of a political movement's power is dictated by its membership?
Even if the open windows of science at first make us shiver after the cozy indoor warmth of traditional humanizing myths, in the end the fresh air brings vigor, and the great spaces have a splendor of their own - Bertrand Russell
