Well...
Imagine you grew up with the equivalent of sesame street preaching martyrdom is glorious- and the people you grew up with echoing that.... Do you really think that your innate sense of right would be what it is today? It was heartwrenching to see 12 year old girls advocating martyrdom in that program...
As I said, the documentary exposed the VERY clever social engineering being done to create the next wave of suicide bombers. Some kids here are brought up to believe in 'White Power' (Look up the music of Prussian Blue) Those sick kids dont have a society believing in that- just a small grup... yet they are true believers.
The militants very cleverly targeted the children, and based on the documentary, they were astoundingly successful....
