I know many, many people who go to church or who say they believe in God. I don't know any who have demonstrated any eagerness to kill people or get other people killed because of their religious beliefs.

Our governments don't kill over religious beliefs, they kill over money, resources, markets, and control of worldly circumstances of one sort or another. They kill in their endless search for temporal power, wealth, and dominion. They kill because they are competitors for those things.
