I would imagine that a statement as outrageous as that printed in the headline to this thread would have been pounced upon by the various mainstream media outlets.
Had a Catholic Cardinal said verbatim..."Israel is a baby-killer", you know that there would be no shortage of TV and internet outlets who would give it airtime.
I've seen exactly one link to this piece; at Jihad Watch, which is where I presume the poster first unearthed this gem.
I'm suspicious about the quotes because Meotti, the author of this piece has been in the news quite recently for plagiarism, so it wouldn't surprise me if he played fast and loose with the Cardinal's words.
I would certainly HOPE that a Roman Catholic cardinal would not publicly make such an outrageous statement - especially not someone in charge of "culture". I also did some searching online and found the article at both Jihad Watch and the one linked in the OP, but nothing on the guy's complete speech. Perhaps it is the author's own interpretation of words the Cardinal spoke or perhaps the Cardinal has said those words in the past or words to that effect. I doubt he said them at the introduction to the last book of the series written by the Pope on the boyhood of Jesus. Such an incendiary phrase would be totally out of place for the venue. The article did, however, bring in additional statements and actions of other religious leaders (the 100 named in the OP) that would lead readers to think Israel is being unfairly slammed especially in this latest round of playing chicken with Hamas.
I don't think it is helpful to the discussion to accuse others of stupidity, of being mouth-breathing idiots, tools of Satan or blatant, intentional, evil liars all out to hurt the Catholic Church. Such knee-jerk reactions at the slightest criticism starts looking like persecution or martyr complexes.
