To me the negative connotations of the word "Redneck" always were about people being willfully ignorant of the world around them. Like, the ones I get at work that piss me off are people who seem proud of how little they know about their own computer, and absolutely refuse to learn anything. Those rednecks need to die the hell out.
Now if you're a guy that works with his hands and just enjoys being dirty in your free time, fucking go for it! I don't understand the appeal of a lot of "Redneck games" so to speak, but there is enough misery in the world, whatever recreational activity makes you happy, do it!
