Thats a massive cop-out Keith. Of course he would heal the daughter of a centurion, he would even heal the centurion himself I believe, but that does not mean that he had no objection to him being a centurion. "Love your enemies", didn't he say that? Religion is often invoked as a defence of nationalism, but the consistent Christian position is in my view theQuaker one.
You are right in your earlier post of course that plenty of atheists have been violent murderers too.
Michael, I think that all of your examples are ones in which religion is commandeered as a justification for violence whose real motivation is a thirst for power. ISIS, thats another matter.
