Even if theism is a failure, it's still superior to atheism

[Angrboda]

It's a laugh that ROt thinks that the religion which is trying to drag the world back to the 7th century actually brought us to a higher, more civilized level.  

No, Islam was a disruptive influence.  It did more harm than good.  It destroyed more than it created.  Roman and Hellenic civilizations make Mohammed and his thugs look like neanderthals.

Not completely true. There is a LOT of mathematics and early science that was developed under Islamic regimes. The Bayt al Hikma was a center of learning for centuries before its destruction by Mongols (who were also not nearly as uncivilized as the stories say).

The problems arose when the fundamentalists took over. That is what destroyed anything good in Islamic intellectual culture.

Exactly how does that make what I said not true?
