Neo-atheism is the polemic of writers like Richard Dawkins, Sam Harris and Christopher Hitchens who disparage and refute the Bible. Unlike their atheist predecessors, they exhibit a ferocious antagonism towards religion. Neo-atheism promulgates a zeal for evolution and Darwinism, exemplifed by Dawkins being described as Darwin's rottweiller. The difference between other atheists and neo-atheists is that the former rarely push their views on anyone, whereas the modern neo-atheists are essentially anti-religious activists.
