That is not surprising. There are no Islamic or Arab nations in which the Christians population is increasing.

In fact, so far as I know (I only know the Levant) there are no growing minorities in any Levant country, other than in Israel.

The Wikipedia article doesn't really support your view that they emigrate to Israel:

>In 2007, the year Hamas took over Gaza, the Gazan Christian population was at 3,000.[5][33] Israel's subsequent blockade of the territory accelerated the emigration of Christians, with many going to the West Bank, the United States, Canada, or elsewhere in the Arab world.[5]

I think they don't. I think it's as states, that they either emigrate to the West Bank or go far abroad.'

There are extreme efforts in Israel to push Christians out of certain neighbourhoods, for example, in Jerusalem, where people have been going after the Armenians.
