I don't think I was playing "Who had it worse?". My point was that if the fairly persuasive theory that interruption of cultural or famalial cohesion that might have enabled a memory of a historical culture could explain certain things, then if we made a rank order of the rates of "success" of ethnic groupings we should be abe to identify the factors that did or didn't interrupt the continuity of knowledge of their ascendants.

Sorry if that wasn't clear.
