Here's how it works: The right of a people to pick their own leaders is good. Countries with this system are generally good.
Leaders who rule without the consent of the ruled, kill and torture people who disagree with them are thought of as bad.
The incentives that support leaders in these systems are opposite. One encourages peace. A leader who is always at war will be voted out. In an evil system, the opposite is true. Thugs must keep the populace fearful and destabilized. Fighting constantly does that.
There are good people who are Muslim, there are bad people who are Muslim. There are good Christians, and bad. What we're dealing with here are systems. At this point in history, bad people are sucessfully using religion to creat evil systems. That's where our fight is.... We fight the part that is bad, prop up the part that's good. Pray for the people. All of them.
