Let's follow this logic then about appropriateness. Back in my younger days, I was a big Hank Williams Jr. fan. On the Whiskey Bent And Hellbound album is one of my favorite songs, O.D'd in Denver. It's about how he met this woman who is the ideal woman, but he was so high on blow that he can't remember her name. I used to listen to that song when my kids were in the car, in their younger days (still do). For that matter, I would listen to the original version of "Devil Went Down to Georgia", the original version of "Fancy" and "If You Don't Like Hank Williams..."
Was I wrong in listening to that music in the car, playing it in family functions, and letting my kids own said music. What one person finds inappropriate, another person finds fine. Now, "cocaine" and queers, yeah, I can understand why you wouldn't let that in an elementary school, (it is a public school though...) but to exclude a song cause of a reference to alcohol. Do that and you exclude the majority of country music from eligibility.
I'm sure you can find a country song that doesn't involve sex, drugs or alcohol... maybe one about a car, a dog, a train or church....
