I agree, it seems off topic to me.
Yes, it could be split off.
I would only add that coming from neither a Russian or Greek background I have a problem fully understanding either concept.
Similar concepts exist in pretty much every Orthodox land. The Carpatho-Russians (and others from that area) might be the most prominent exception, for obvious reasons.
How does either really relate to the mission of our Faith in a modern, pluralistic society comprised of all races and religions?
The role of all
religions -- and the nature of "identity" itself -- is uncertain and fluid in modern, pluralistic societies. Figuring out how to navigate these new waters with faithfulness to the Gospel and our Orthodox heritage is one of our greatest challenges.
