Israel is a notable exception as a country in the Middle East where Arab Christians can thrive, perhaps even more so than in Lebanon, and also happens to be the actual place Christianity began. That is very relevant to the article and no doubt the author is well aware. He just went out of his way to avoid portraying Israel in a positive light.
I disagree.
From the first few paragraphs of his article:
....We will recall that they then fled to Egypt as political refugees.
Two thousand years later, the Christian communities of the Middle East — descendants of the first Christians — persevere in their faith in Christ. They live in an era of violence, unrest and persecution. Many have been forced to flee their homes and many more their countries.
That is the topic of his article. A polity where there hasn't been any persecution of Christians in the region, nor is there a threat of such, is simply not part of the discussion.
You should also remember that he's an Arab, and looking at it from Arab perspective. He might feel that Arabs are class 2 citizens in Israel (I'm not commenting on whether that is true or not), but that has nothing to do with Christianity.
There's enough real antisemitism in our backyard, let's not look for it where it might not be there.
