For what it's worth, I didn't mean any offence by it, either. Brits are known for the most part as Corgi humping tea drinkers, lol. Being able to laugh at stereotypes is one of the best facets of human experience. It leads to way less X posts. Is why movies like Austin Powers and Talladega Nights work so well.
I remember back in my navy days, we used to have an acronym for the Marines. It wasn't done out of anything but love and gentle ribbing. Muscles Are Required, Intelligence Not Essential. Of course we all had the utmost respect for these folks for whom 90% of the entrants, mostly from the navy, wouldn't last a week.
I agree with Jess, though. Redneck can be a term of endearment. I am somewhat of a fan of WWE, and one of the biggest names in that, Steve Austin, was known as the Bionic Redneck.
Coming from a country where formula one is a thing, with corners and stuff... it's hard for us to understand why driving in a giant oval is challenging, lol. But the speed these cars go... I've seen the final destination movie. One tiny movement can lead to a massive, life threatening crash. You're going full speed all the time. And the cars are insane, juiced up monsters. Nothing like we'd use in the UK. It must be like wrestling a bear just to keep them on the road.
