Raymond Ibrahim joins Brian Lilley to talk about the persecution of Christians in the Islamic world.

Ibrahim: Wherever there are sizable Muslim populations living side-by-side with Christians, the latter are under attack. So, yes, Christians are being persecuted, to varying degrees, in all Muslim nations. The ultimate deciding factor is numbers—comparative numbers of Muslims and Christians, that is. The ratio of Muslims to Christians in any given country—or, looking at it another way, the proximity of Christians and Muslims—is the primary factor explaining which countries see the most and the least Christian persecution.
