I’ve been reading a very interesting assessment of the religious conflicts that have been fomenting around the world these days (well, actually, religious conflicts may be the lone absolute all civilizations have realized ad infinitum).
The problem, that has developed into terroristic behaviors according to my very credible source, is disenfranchisement: a lack of opportunity to voice grievances by participating in a political dialogue. Giving marginalized peoples the opportunity to be part of the legitimate social/political structure has been shown to reduce extremist behaviors and even groups with fairly hostile inclinations, people who view non-believers as apostate or heretical, will, given the opportunity, most likely work within a legitimate structure.
So, perhaps, rather than preparing for a cosmic war, opening dialogue, developing mutual trust, bringing the outliers into the fold is a superior philosophical stance. Besides, who can really know which side God is on?
