Speculation in Vatican section
The paragraph quoting Francis Cardinal Arinze ends in POV speculation:

"There are some other religions which if you insult their founder they will not be just talking. They will make it painfully clear to you," 

This is followed by the speculation:

The apparent reference to "other religions" is to the violent protests against the depiction of Prophet Muhammad in cartoons.[2]

While I'm not going out on a limb to defend the violent protests, is there a quotation or source which indicates that is who Arinze was referring to?  Until there is affirmative followup, I'm removing the last sentence.  09:17 20 May 06 GMT
