Country used to be very rough and earthy. as did the people listening to it before the 1970s and pot reached the country world. "Knoxville Girl" is kind of a shocker, it was a hit from a very popular duet, the Louvin Brothers.
Here is the song that reached number 19 on the Billboard Country Singles chart in 1959, "Knoxville Girl"
""It’s perhaps their most powerful rendering of traditional folk music’s bleak vision of a dark and forlorn land, where love is absent and death is the only certainty. It’s the centerpiece of what is arguably the Louvins' finest album."The album is also included in the book 1001 Albums You Must Hear Before You Die."
There are some more examples here. Violence is a part of our folk music history
With all due respect this is part of a genre sometimes known as “Hicksploitation.”
To me it’s like comparing Stephen King to Mark Twain.
