It's great when Arabs emigrate from Israel. There is almost no difference between Arab Christians and Arab Muslims.
Yes both hate Jews however, the Muslims seem to be kicking the Christians out of the country at a rapid rate. Cities like Bethlehem are largely devoid of Christians. Of course nobody gets worked up about it. Obama has not claimed to be insulted by it.
The problem with Muslims is that they don't leave. They will live in the cesspool of Gaza rather than leave. I know Chaim always cites that study saying they want to leave but if they really did they would. Haitians, Mexicans, etc. seem to have no problem leaving their hellholes.
