I think the point is; if the bible itself says it is to be taken literally, but it's stories don't jive with the real world it's foundation as an infallible religious text is built on sand. If one subject xan be questioned, then all of them are in question.
That would certainly be true if the bible said to take it literally, but to the best of my knowledge, the bible doesn't say that.
I think the bible says it's not ok to get it wrong though, right? I know it's hypothetical; but if you start a new religion based on the New Testament only, that's not going to jive with all its references to the Old Testament. And now man has created the religion and not god. The religion has become the crutch for the belief system of the individual(s).
The bible itself is full of people getting it wrong but being looked upon with favor by God. Man definitely did create Christianity. Hell, most of the ideas about God that people have are highly anthromorphized and man-centric. That only says something about us - not about God, however you want to define that. The bible definitely models a faith in which you are not expected or asked to have it all figured out, and not only that, but a faith built on trust rather than on 'correct' beliefs.
Religion is the root cause. It plants the idea's into people's heads.
Radical Islamic terrorism wouldn't exist without religion. The westboro baptist church wouldn't exist without religion, etc.
And I know WBC hasn't killed anyone. Just a hate group using free speech to their benefit.
What about the atrocities of the Soviet Union, Nazi Germany, Cuba, China, and North Korea, all official atheist state communist regimes?
