"Holy War" is an offensive oxymoron

Let me see if I have this right: The Pope, in a long discourse that involved historical themes, offends Muslims by (according to them) implying they use violence to impose their way. So a few of them go out and shoot a defensiveless nun. How dare the Pope insinuate that Islam has a violently radical element! Here's the deal: If any religion pushes violence, under any circumstance except defending yourself from an ongoing attack, then it's showing a nasty human side that has nothing to do with God or Allah or whatever you want to call him.
