I have a different perspective, having lived in the Middle East among Muslims. The Western mind cannot conceive of the madness that infects the mind of the typical Muslim. Not all are bad, by any means, but a significant minority are so damaged by their hate-filled religion that they lash out violently and irrationally at the slightest provocation.
And then there is the IQ matter which we must honestly fact-—the IQ differences between ALL of Africa, including Somalia, and the West. LARGE differences.
Polls regularly show that across the west and MidEast, Muslims who have never directly participated in Jihad or terrorism support it by a large % and support its most extreme manifestations. The peaceful muslim you see in WalMart or in your office, when given the “high” sign, the right sign, can immediately turn into a jihadist.
This goes back to your central point. Their hate-filled youth and education reinforced by hate-filled adulthood.
In the case of Noor-—not given a “sign” per se, but rather TRIGGERED by a highly-charge situation in which he was confronted in seconds by several dynamics of the hate ingrained in him and to which he is sworn to act on: woman in public not covered, barely clad woman for his experience, impudent woman not “knowing her place”, an INFIDEL blaspheming Allah...a conflation of things that, to Noor, militated the murder of the female.
