They added that in because people started getting up their ass about "Muh Islam" and "Muh Crusades", and frankly, some of it went both ways. This was 2007 and things were a bit tense back then, what with Bush still in charge and the FBI finding a schizoid Muslim to groom as a terrorist every six months, or so it seemed. Clearly "Get bent, faggots" would have been a much better thing to say in hindsight, but for a game in 2007 to pull some sort of ass-covering about how they're totally not for or against any religion whatsoever was a smart bet. Obviously they should have dropped it once they went to Italy where it was Christian-on-Christian violence, but alas, frogs gonna frog.
