I can honestly say this...issue...never crossed my mind before reading this thread. But now that it has, it occurs to me:
- In junior high and high school I knew (vaguely, we weren't friends) an Indian girl who sounded just like the other preppy girls she was friends with. And this was the 80s-90s so think Valley Girl.
- Knew two guys, brothers, who were born and raised in New Jersey and sounded it. Asian ancestry of some kind, maybe, who knows, or Maori.
- There was an exchange student from Sweden. Try to imagine a blonde white girl using late-80s rural-Southern-US-black slang with a Swedish accent.
- Went to college with a black guy from London who had spent a few years in his teens as a homeless thug before getting his crap together and back in school. One of his good friends was a white girl from Germany who'd been raised in France before moving to England.
- I know a girl who's Chinese-Swedish, raised in Brookyln.
- Ever watch Outside XBox on YouTube? Jane Douglas, that is all.
So yeah. Not really an issue.
