There is a good article in the Guardian about how the new "militant" Atheism will fail to challenge religion, in large part because of its tactics and attitudes. And it's in large part correct.

However, every world view has moderates. And they typically grow when there are extremists providing a nastier alternative. The Kinder, Gentler, Atheist will thrive.

Have you noticed how well Islam has grown since the Shia started kicking Western ass? Or how popular Evangelical Christianity has become in the US since those nutjobs started yelling louder? Hardliners are good for an Idea. Especially the subversion ones.
