NCF: for accents, I'll have to listen at 1x (I normally listen at 2x or close to, which tends to turn all accents into Mickey Mouse)
But a priori I'd generally say: show me someone who doesn't code switch, and I'll show you someone who's always been unmistakably a member of the dominant subculture.
(rummaging through NCF's biography* it's no wonder we come to different treatments for the same diagnosis; he wants to convert the losers [back?] to clueless by infusing them with national spirit; I'd wish the losers could become psychopaths by having [per Aristotle... or Jefferson] some business of their own which they could mind. Regardless of which one of us is correct in general, if one believes in late soviet America, then I'd think one might think that attempting to Tinkerbell [in whom the panto audience must believe] one's way out of it is likely to be as effective as it had been for the soviets, or at least among those among them who hadn't been athletes, scholars, and Komsomol members)
