Something that gets completely glossed over in the news media, amidst the reporting of Shia on Sunni, and Sunni on Shia violence is the fact that thousands of Christians live there too. Unfortunately they get caught in the crossfire and are the subject of violence all the time.
My Iraqi friend that I met in Egypt recently sent me a link to a video that highlights this fact. I will warn you that there is some graphic content in this video, but I think it is important to know how our Christian brothers and sisters are being treated there, so I encourage you to watch it.
Here in the U.S. we largely enjoy religious freedom while these people are constantly persecuted for their religion, which I think should give us a better perspective of the freedom we have.
