Have you ever noticed how unreliable actors are? Just as a familiar face pops up on the screen and you're saying: "look! there's mad Max", it turns out the bastard's pretending to be someone else this time.
In the cases of e.g. Eastwood, De Niro, and whatever that Ozzy geezer's called, it might be said that the roles don't change very much. They're surrounded by different actors and the given a new name for the role, but otherwise, maybe like poets, they have something like a recognisable voice (mien, in the actors' case).
So if a poet should deliberately use a voice as part of the poem, as is the case here, then you may see the difference between the Kevin Costners and the Peter O'Tooles of this world in the extent to which he/she succeeds.
Oh shit, what am I babbling about. Never mind. Is it not such that the aboriginal voice assumed here would be uncomfortable with a phrase like 'ethnic plurality'?
