Same with this, an article by Austin Cline on About.com:
Reasons for atheism vary as do how atheists approach religion or theism. One very common response to claims about gods and the supernatural, though, is "we're atheists because you can't support your claims about gods existing." The
primary burden of proof (or support) lies with those alleging that some sort of "god" exists. In the absence of any evidence or successful arguments, some resort to hand-waving and diversionary tactics which give the appearance of "sophisticated" and "deep" thinking, but which is meaningless unless and until there is good reason to think that the foundation of all that thinking — a god — exists.This is what the defense of theism and religion has been reduced to: it's "hooliganism" to demand evidence and proof, to dismiss empirical claims that lack any evidence or proof, and to publicly proclaim the vacuity of ideas for which people will nor provide evidence or proof. It might be regarded as pathetic that defenders of theism and religion have fallen so low, but was there really ever any other place to go? The absence of evidence and proof in their discourse has long been a problem. The irrelevancy of the hand-waving and linguistic acrobatics in "sophisticated" theology is recognized even by some theologians. Once outsiders started to put those two together and making a public case about it, there really aren't any other options available.
Our scientists used to offer us more. They can again if we refuse to accept Hooliganism as an acceptable form of discourse about the world, and our place in it.
