OK, let's focus upon his religious insights. Please mind that I am an atheist so you can be as blunt as Hitchens has been when repeating them.
Let me point out something about religion I learned from actual intellectuals. First of all, the monotheistic revolution ended paganism. The pagan universe is one of day and night, male and female, day and night. When there is a drought you sacrifice something or someone to the fertility goddess to restore the balance. In the Israelite religion on the other hand there was no such natural order anymore, God stands for the law and this law is intrusive, people have to be forced to obey it. Furthermore God stands for the absolute (Think about the Holy of Holies, it is forbidden for anyone but the High Priest to see not because there is something there but precisely because nothing but the stupid ark is there. The nothing has to be covered to create the illusion of a place where the absolute is represented.) which implies a serious leap in human thinking. Without intending too sound too philosemitic, what you could call the secular Jewish spirit, what has made Jews being overrepresented among intellectuals (which has perhaps also impacted Hitchens due to his Jewish ancestry) had its origins in what Hitchens considers to be the simple superstitious thinking of bronze age people.
Think about the Book of Job, God basically says that everything is a mess and out of his control. Christianity goes on step further, God dies! The pagan game of bribing the gods in order to restore balance is undone, there is a radical cut, we are basically on our own.
Note that actual Christians often think like pagans. The ugly things Pat Robertson said after 9/11 imply that we have to be good such that God does not punish us. Or take the masochistic left-liberal who thinks that Islamic fundamentalism is a punishment for Western imperialism.
Judaism and Christianity teach us that this pagan logic is flawed, we can draw no such comfort in the case of a catastrophe. Ironically Hitchens would have totally agreed with the second part of this sentence, totally oblivious of the fact that monotheism first set us free from the pagan logic of 'catastrophes have a meaning'.
