I don't get it. Pope John Paul II probably just kissed the Koran out of respect for the Muslims who were present with him. It was a gesture of respect, not a proclamation of faith.
I know, I know, there are probably canons against all that and then there's the whole "lovesupreme is a dirty ecumenist who thinks it would be okay if the Pope sacrificed children to Moloch if it meant making the Moloch worshippers feel better" point that you can sling back at me.

I just don't think this is worth getting all upset about. Yes, a practicing Christian probably shouldn't make it a habit of reverencing heterodox religious texts, but Pope John Paul II represented the largest body of Christians in the world, and he needed to show some diplomatic leniency. It would be no different if he bowed to a statue of the buddha when visiting the Dalai Lama. It's saying, "hey, I respect your beliefs because I respect
you." Again, not the sort of thing most people should be doing, but an international figure like the pope? There's a time and a place for everything.
