Zizek does what there? That looks like a review of his "Parallax View" to me.
Seems to me that he takes a specific argument and then puts his own interpretation to it. Also, that he takes a look at an argument through his version of the eyes of someone else.
I think he's a good thinker but he sure seems to try to lose readers in extremely fine detail and intricate little nuances.
Dawkins seems to think we are programmed entirely genetically, even our thoughts. Given his atheistic view, then religion should have died out like a defective part of programming. But it rather seems to have some endurance. If we are not free thinkers then we would not be able to disbelieve but would be programmed to keep religion around.
(Not sure if I explained what I meant here well enough. I'll work on it if not).
I think Hitchens has a good point in that if this god was indeed all-powerful and all-seeing, then it is all-responsible for absolutely everything including an infinitely vast amount of transgressions of its own view of morality and hence turned itself into an immoral being.
