As the article pointed out:
"The largest communion present in Darfur is the Roman Catholic Church, with 143,000 adherents. People also belong to the Sudan Presbyterian Evangelical Church, the Sudan Pentecostal Church, the Coptic Orthodox Church, and the Episcopal Church of the Sudan."
That means that given even a miniscule 17,000 for other Christians in Darfur (I'm giving you the benefit of the doubt, though I don't have any legitimate reason to), the Christians in Darfur comprise a minium of 6% of the 2.5 million displaced and or under attack there. Yes, that is smaller than the Muslim's under attack - so what.
Why is the size of the Christian population there, and your need to minimize it, so important to you?
