It's PC people. Rednecks tends to use slurs (ad with them, you know where you stand with them, no guess work required).
Gabriel Iglesias once did a joke about having to go half way around the world to be considered an American comedian.
My ex boyfriend told me a redneck is a
guy who'd help you change a flat, give
you the shirt of his back, lend you
his dog and give you ten dollars.
Guess it depends.
I led a different sott of life than you
in the USA, most of it was " upper west side "
Manhattan.
I did though make trips all about, including
longish visits to a ranch in Wyoming.
(Home of friend from college )
I must say, those cowboys and ranchers were terrific people! So welcoming, wanted to
show me everything, get me on a horse,
"help" with branding, ..those for sure
are " shirt off their back" people!
They were curious about me, but never once
made me uncomfortable.
Which honestly, pc folk often enough make my skin crawl!
