The persecutation of the Christians is nothing to so with the teachings of Islam....indeed when Umar Ibn Khatab (the Companian of Muhammad) ruled it was the golden time for the Jews and Christians.@Ozada: There are plenty of Christians living in majority Muslim countries. In fact, many of the countries in the Muslim world were Christian countries until the jihad conquered them. Christians are still being persecuted and dying for their beliefs in these countries to this day.
They could worship in their churches and were protected by the Muslims.
....today none of the so called Islamic countries rule by full Shariah due to their corruption.
