On persecution of Christians in the Middle East

"Some of the most systematic terrorism in the Islamic world has been the daily persecution of Christians".  It is fair to say that the state persecution of Christians in the contemporary Middle East was first observed in the regime of Anwar Sadat of Egypt (your client and your choice, not ours) and in Iraq after the US invasion.  But what is curious to me is that no one mentions the Christian persecution of Muslims in the Middle East: Lebanon until 1991 was a state dominated by right-wing Maronite political forces and the modern Lebanese state institutionalized discrimination and persecution of Muslims, which was one of the causes for the civil war in 1975.
