Quite a number of historical inaccuracies in the post above. Crusaders did resort to rape, as the sack of Constantinople could attest, even if the First Crusade was allegedly limited only to indiscriminate massacres, cannibalism and forced conversions. Of course, isolated cases of rape also occurred, albeit not in a systematic scale. There were religious wars involving western Europe even after Westphalia, such as the Holy League of Pope Innocent XI. Finally, the fifth point is completely misleading, but also often used nowadays to sow discord among fellow citizens. Taqiyya refers to the possibility of Muslims hiding their faith, when their life is threatened by bigoted authorities. It only concerns religious affiliation and is only allowed in times of violent persecution, although martyrdom by refusing the forced conversion remains the preferred option.
