I suppose I ought to comment briefly on the Pope and his words about Islam. But pretty much everything there is to say is obvious, so I'll do it by quoting someone who said it better than I could.
The point is, if you want to undo stereotypes the best way of doing so is not to blame a person who supposedly reinforces a negative stereotype, but in reacting in a way that different than the stereotype. The stereotype of Muslims tells us that they would react to the pope's words with anger, violence and calls for blood. Sure enough, many Muslims reacted with anger, violence and calls for blood. So who is reinforcing the negative stereotype?
Yes, it's a war. Yes, we as Christians are probably going to have to fight it. I hope and pray we're not going to use violence in doing it, because that would be really stupid.
This might be for some an occasion to dig out that great victory hymn from the book of Revelation.
They overcame him
by the blood of the Lamb
and by the word of their testimony;
they did not love their lives so much
as to shrink from death.
Revelation 12:11, NIV
This is not talking about suicide bombers - this is talking about people winning by being willing to die (rather than to kill) for the one whom they love - Jesus. And yes, I know in context it's talking about defeating Satan, but the principle holds the same.
