It's not the government that is cleansing the country of its Christian population. It's the anti-government rebels who are doing that. Asad has been very tolerant of religious minorities, and Orthodox Christians have lived in peace under his regime. Yes, he may be a dictator, but it's not like the rebels intend to set up a Jeffersonian democracy either. And whereas Asad allowed Orthodox Christians to live in peace there, the rebels are trying to get rid of them.
You're correct, Salpy. Thanks for pointing this out. I apologize for making the story seem one sided while ignoring all the nuances. Yet I will say that Asad, as the leader of Syria, does bear responsibility for protecting his subjects. I don't see a lot of effort on his part for bearing this out. But, I could be wrong.
