I'm sorry to say this but I do not like country, either. I feel pretty open to most types of music, but not much with this one.
I heard it a lot growing up. That was the age of stuff like the Dixie Chicks (saw someone else mention Shania Twain, she had some cool stuff in the 90s) and some of their old stuff I would probably still listen to a little today if it came up. I didn't really mind country growing up, as a kid you don't care as much about the music you hear and you don't have as much control over it, either. I think it's declined a lot in quality in the past decades. If I think of a few country songs I may enjoy, they'd be really old ones from decades ago...now, country is heavily pop-based (inherently I don't care but it is a bit hypocritical) and as others have said, it mostly seems to be about drinking, picking up women, sex (in a really weird way like if you were listening to your grandparents talk dirty...no one wants that), and I'm not very much in agreement in general with the demographics of country music (political and religious views for example), so there's that. I also think it's a bit hypocritical that they have so many songs about getting drunk, but would have no problems giving someone a hard time for using cannabis. I'll never be ok with that mentality. Another problem I have with country is that, despite the things I said, it's just 'ok'. It's the 'accepted' genre of music you hear in most restaurants or stores because people just assume country could never offend anyone. My parents also liked classic rock and some modern hard rock but nope! When relatives come over, they would only play country. I'm not saying it offends me, but it's not the most amazing, sacred music, either.
I understand that some of what I said against country can be applied to say, rap music. Lots, not all, (like country; some, but not all) is about sex, violence, intoxication, etc. but at least it's not trying to claim it's something it isn't, and I get that vibe more from country. Those themes also suit rap music more, in general (there's plenty of rap though that is extremely intelligent and inciteful if you listen); I listen to it when I'm with friends or the like. With both genres, there are good and bad apples. I mainly made the comparison to rap because a lot of people who don't like country may not like rap either.
