You are blind to the diabolic nature of Islamic terrorism.
They are not “Darwinians”.
You are delusional to think so.
But par for the course with you, you suffer from a myriad of delusions.
Islamist terrorists have departed from traditional Islam by incorporating the moral nihilism of Revotionary Materialism. But again, the reason you are incapable of grasping this simple fact is because you are a materialist at heart yourself, and thus you have a huge blindspot in this area. The only solution is to ask God to make the materialist scales fall off your eyes, otherwise you will forever be blind in this area.
