The stereotypical Kentuckian is aggressive, unafraid to confront someone, die-hard republican, anti-equality, and probably very much in support of the Confederacy despite never having joined it. That, to me, does not create an audience with which I'd like to share an amusement park.
I have lived in Kentucky my entire life, born and raised here, and am as different from your description as you can get. I am not an overly agressive person. I am a life-long Democrat, as is, believe it or not, most of the registered voters in my part of the state, which is the southeast part of Kentucky. I believe in equal rights for all, no matter what race, religion, or sexual orentation you identify yourself with. I do not fly the Confederate flag and would have enlisted with the Union if I had the misfortune to have been alive during that terrible part of our nation's history. I am not white trash and do not, nor have ever, wore a wifebeater.
You are correct, there are plenty of rednecks and white trash types from Kentucky. There are also plenty of good, hardworking, honest folks from this state as well. I have travelled around quite a bit of our great country, and have seen rednecks, white trash types, thugs, and other assorted hooligans in ever state I have been in. Don't put down an entire state or group of people because some of them may not be the best type of person.
