The ugly rays or prejudice are flowing out of @filmfann today. You’re painting with an awfully broad brush, and making some rather huge and sensationalistic assumptions in what you wrote.
First off, Muslims aren’t inherently scary or worthy of derision. Some are, sure, just like some Baptists, and some Jews, and some of any religion you choose. So talking to or honoring Muslims is not inherently suspect.
Secondly, I give this new pope credit for not being trapped behind cloistered towers and talking only to Catholics. This new guy knows that the world is made of different people and different religions, and he seems to accept that one can learn from the good (and the bad) in other religions.
Finally, I thnk that your comment (Is the pope a muslim?) is trying to create guilt by association, which seems a rather shaky tactic.
