I think the author is saying as such, Koco/ER, when he states/speaks of:
"The truth, alas, is that the science fiction archetype of the mad scientist who craves to dominate the world has been replaced by the mad cleric who can only conceive of the world in his own image, proudly flaunting Bond's Double-0-7 credentials -- Licensed to Kill"
I read it as the "you" was understood in that it is/was man(human beings) who/that created/concocted all these religions that extract the worst from humanity in the first place.
In my view, he should has used the words "organized religion", however, he is speaking from a perspective relative to Africa, I on the on the other hand, see what he has to say as true throughout the entire world.
I too, also believe that religion is the origin of the hate, evil, extremism, racism, sexism and crimes against humanity, not just in Africa, but throughout the world. I too, also believe that, religion/organized religion, has been given a free ride regarding its part in the corruption and depravity of humanity.
