Personally, I think discussions about grammatical rules at this literary elevation are about as useful as comparisons of a turboprop with an F16.

Sorry to have bothered you, but I thought the original posting asked a question about whether the noun diaspora could modify the noun Moroccans. I could be wrong, I probably am, or I could be digressing, but heck, that's pretty much SOP aboard the good ship HMS AWADtalk. Folks purdy much talk about what they feel like talking about.
