Two high-profile incidents last week, at opposite ends of the Arab world. In northern Iraq, recently conquered by the zealots of the newly proclaimed "Islamic State," the Christians in Mosul were given three choices: convert to Islam, pay a special tax (about $750, on this occasion), or be killed. They all fled, and now Mosul is Christian-free for the first time in almost two millennia.

Meanwhile, in Sudan, Meriam Ibrahim finally got permission to leave her homeland after spending months chained up in a jail cell. The young woman had been condemned to hang by a Sudanese court for the crime of having "converted" to Christianity, but the government couldn't legally kill her until after her baby was born.

Now, neither of these incidents gives an accurate picture of government policy in Arab countries that have traditionally had Christian minorities (which is to say, most of them). Indeed, big Arab countries like Syria, Iraq and Egypt have all had Christian ministers in their governments, and their laws guaranteed religious freedom.
