LOL!
I will presume that the Pope is just trying to be the consummate politician, and thinking that you will catch more flies with honey, rather than trying to bash them with a 2x4.
Nonetheless, obfuscating the Truth helps no one. Not those being persecuted by the evil and violent religion of islam, nor the muslims themselves. It would not hurt to state the facts: Islam bares no resemblance to a God inspired religion, however it bares signs of having been inspired by Satan: their prophet admits that he was once fooled by Satan because he was wrong 'once' (and the real Bible tells us never to believe a prophet who delivers a false prophecy); it encourages its believers to kill; it has a 1400 year history and legacy of leaving death, mayhem, and destruction in its wake. Given that Satan hates people -- I'd say that Islam IS Satan's religion. Prayers to the people afflicted by it, and prayers for those that have been duped, or cowed, into falling it.
As the 14 year old said "You're blunt, as in you leave marks".
Like your screen-name, BTW. I do a lot of reading from that era. If you are talking about Rodrigo Díaz de Vivar, the Moors are the ones that called him 'El Cid'.
