The holiday is a fig leaf. You would know this if you follow the news. The Christian Exodus has been going on for years but after Bush invaded.
At least CNN covered it. I can’t think of a single article in the neocon press, or by by neocons, on this.
Ay...that following the news thing is very bad for you. It can lead you to believe things that are not true.
Yes, there was an exodus of Christians, beginning in 2004.
They began returning in late '07.
Christian (mostly Chaldean) churches began opening again in Baghdad in late '07 and more throughout '08. They are being attended regularly with little to no trouble.
Christians in Mosul are still struggling because al Qaeda hasn't quite been shut down there. Yet.
Iraq was a secular country that accepted Christians before the war and those roots are returning.
