Hi Paul, My two cents  (a penny for each) on the letter.
The Imams like all religious holy-men (can't use holy-women in Islam) will rationalize a way around the feeding to the pig thing.  It will most certainly backfire by ticking the Islamic terrorists off even more and make them fight harder, not to mention swing some fence sitters to their side.  This kind of stuff is more a motivator for many of those who are willing to do our fighting for us.  It is best to keep this kind of stuff in house, regardless of how humorous one may think it is.

His second thought I think is more ironic than sarcastic and I think is an interesting and thought provoking point.
