The one common element in these cases of spontaneous "radicalization" seems to be exposure to a certain book and a certain so called religion, "of peace" no less. Maybe quarantine for those heavily exposed is advisable. Say, in countries already overrun with hopeless cases, large scale leper colonies so to speak. It would be the prudent and humane solution.
I’ve been wondering the same thing.
RADICALIZED. It’s like popcorn finally pops.
