Extreme Atheism? what? as opposed to being a little be atheist? (I thought if you advocated that you're an atheist, then your an atheist... no real degrees of atheism (it takes the acceptance that there's no god to qualify for the job

) )
Anyways, Atheism is based on looking at things in an analytical manner... You don't accept the existence of god due to information you've been given... so you being critical to deduce there's no god (in your own beliefs of course). So Atheism would naturally allow you to distinguish from reality and virtual reality given you became an atheist due to critical thinking.
Blind faith (which would be what the majority of believers practice) requires you to dismiss anything that doesn't bond well with your beliefs... So if you think that Rogue in WoW is real, you've already been trained via religion to dismiss the arguments of others against your believes, so you'll believe it's real come hell or high water
