I was raised mostly in Kentucky, but I've lived in WV for 18 years. To me, yes, they are rude. For example, some men came to work here on the parsonage. One of them yelled at me because I let my dog out to go potty while they were working and they had left my fence gate open while they were out there, and my dog got out. Completely his fault, not mine, but he literally raised his voice at me over it. When my dh came home, the man acted all nice like nothing ever happened. We've had missionaries over to eat with us, who would not talk to me or even look at me or our children, even if I asked a question, but would ignore me and talk only to my dh.
A local pastor would not even return a greeting of hello or handshake while at church, but warmly greeted my dh. (Although I suspect this was because I was wearing slacks and I think he has a problem with that.)
Recently I babysat 3 children all day long, one of which was an infant, and I cooked dinner for a family because the wife was unable to do either. The husband acted like I had the plague, refused to talk or even thank me when he brought the kids over and picked them up. He'll talk non-stop to my dh, but won't give me the time of day. Even my dh noticed it and was confused.
