Are the Muslims building the Ground Zero Mosque insensitive or do they 'suck'?

An interesting piece but I was staggered to learn the title of Iman Rauf's book 'A Call to Prayer from the World Trade Centre Rubble: Islamic Dawa in the Heart of the America Post 9/11'... In case you don't know, dawa is the means by which the Islamic Prophet Muhammad spread the message of Quran to mankind and modern Muslims do the same now..
