There is something wrong with interfaith dialog when one side uses words and the other side uses fire bombs. His Holiness Benedict XVI has said that reason should be the basis of dialog and that violence should not be used to compel conversion. In response, representatives of Islam have taken to the streets and are fire bombing Christian churches that don't even acknowledge the Pope.
The nature of the Islamic deity is quite something, rewarding those who murder in his name with 70 virgins and so on.
