Afrikaner friend is posting about how families leaving South Africa for the USA look like evil rednecks and obviously stupid. Other friends are chiming in how Trump is sending away Afghanistan refugees and that they're the wrong color, and that's why.
Then the English friends are posting about how Afghanistan being a terrible place and sending people back is a terrible thing. Meanwhile South Africa is a great place and no evil horrible thing is happening.
It's been going like this all day.
The term 'Redneck' was first put to paper by a female journalist(surprise!) as a classist insult because she wasn't one of those low-brow other people, no sir. She was better. (She was totally a fucking redneck who married into money.)
Rednecks, not giving a fuck(as far back as the 1800s while this was going about), took the term and ran with it.
It's still used as a classist insult today.
Fun aside, the term redneck actually pre-dates hillbilly, near as I can tell.
Despite the Yankees and Media trying to use all these terms as meaning the same thing they do all have wildly different meanings.
Redneck, and white trash, are the only ones with general enough meanings that they are usually accurate subjectively, but they will happily throw in shit like hillbilly about someone from a fucking swamp.
