West will not win against crazy groups by reimplementing the great firewall of China. If the state wants to control our lifes, they should have real time access to credit card and phone data. One main issue is religions and that it turns people against each other due to different beliefs.

general education and broad tolerance between cultures (either religious or not) is quite probably the only way to move towards non violence and peace ...
