If you knew the area like I know the area, yes it is rather red neckish..
Whats with the casual use of racial slurs? In your mind, is "red neck" somehow less offensive than "fruit picker" or "porch monkey"?
I have no problem being called a redneck. And is redneck actually a racial slur? Unlike the ones you listed, "redneck" is not a slur for all white people. Redneck is something you are because of where and how you live. You know, based on your actual individual life.
I hunt, fish, own guns, like my pickup truck, can build a fire, and have spent enough time outdoors with a shirt on to have a farmer's tan. Sounds like a redneck to me.
