Looking into what brings about willingness for jihad it is inescapable the "steps" required for radicalization are the same as for a cult.
Critical thinking has to be disposed of. A sense of being better than others. Sexual activity suppressed. Sense of humor has to be gone. Sacrificing oneself to save mankind.
Stunning how it take the same thing kind of steps to get closer to the " goal ".
( Please do note I'm talking about RADICAL only ! )
One odd thing I'm not sure exists in scn that exists in Islamic radicalization is beauty is eased out & attention is put on ugly - eventually no beauty can be seen - makes it easier to hate. That is the ONLY point where I didn't see the exact same pattern.
