Sadly, every year some great 20th century person passes away... this is in the nature of our mortal being. Much mourning is being done all over the world, so I think many people feels not the need to express it even if they feel it in their hearts. In the end, IMHO what this Pope would like it is more respect for ALL humans beings and more dialogue to end wars and incomprehensions, not great memorial speeches. If you want to do him honor, honour him in actions and not words :)
