evil?

Alright, here's what I'm struggling with. I'm living in Burnaby, B.C. right now with some very dear family friends. They treat me wonderfully--as if I am in fact their granddaughter. The grandfather figure, Gerry, is getting older and has leukemia although he's in remission right now. I have enormous respect for these people and the way they open their house to anyone and everyone. They are part of many peoples' support networks. Now, as I said, Gerry is getting old. And as he ages, he seems to narrow the way he thinks about the world. He also seems to get stuck on certain topics. Almost every day he tells me that he is worried about what the world will look like in 50 years because of the frightening threat that the Muslim world possesses. He read a short book (written by Christians) about Islam--he's tried to convince me several times that I need to read it, although I told him that I went to Egypt and took a course on Islam (although certainly not comprehensive :)) and I believe that I know most of what's written in that book. Almost every day he tells me that the Muslim philosophy is that if you're not a Muslim you don't deserve to live. While he's not totally wrong on that point, he's not toally right either. He's convinced that all Muslims are evil.

So here's the dilemna: how do I talk about this with him? I respect him immensely--he is a very faithful man of God. He grew up in Germany under Hitler, so he knows better than I what it is to suffer under a dictator. Sometimes I try to point out that Christianity doesn't have a totally clean record either, but that doesn't seem to make much of an impact. I'm frustrated because it hurts me when a man I love tells me that the wonderful family Claire, Dena, Amber, Marcia and I met in Alexandria is evil, or my host family, or any of the women who smiled at me shyly on the Metro. If they're evil, so am I. I guess that's the answer, eh? We're all evil. I know I certaily don't deserve anything I have, much less salvation. Any ideas? What should I say--keeping in mind that anything I say he will probably forget or simply refuse to listen to?
