It seems that many, if not the majority of the users on this website define their atheism only through an anti-christian lens. I don't understand the focus on that perticular religion. Atheists should look at every religion or at no religion at all in order to be self consistent, and consistent with what they decry.
It simply is because, by definition, each religion is absolutely right and focusing on one gives it too much credibility. It is also because there are so many more ideas with which to come up. Sure, maybe everybody here knows how to explain whay the christian god doesn't exist, but can they say the same of Brahma, Vishnu and Shiva? What about Anubis, Thor or Amaterasu?
I guess my point is that you have to ignore all of them or treat all of them equally. Atheism is much more fundamental than anti-christianism.
