What is the point of clean music?

Recently I've been thinking of all the music I used to listen to when I was a kid. When I was about twelve years old, I started listening to bands like Marilyn Manson, Rammstein, etc etc.

As I'm sure most of you know, this music isn't considered to be kid friendly. So I was surprised when my friends' parents were buying them the "clean" versions of their albums. this means that all the songs with cuss words are bleeped out, or have slightly less offensive lyrics.

I understand that you might not want your child listening to a certain band or artist. That being said, if the music is so terrible for your child to hear, why would you bother with buying them the clean versions of the music in the first place? Children are not idiots, and they're going to know what is really being said. And if they don't, I guarantee you they have a friend who does. Any parent who thinks otherwise, probably doesn't have much faith in their child's intelligence.

Ask yourself this. Would you take your nine year old to see the movie Saw as long as there wasn't any blood? Keep in mind, they're still going to see terrible acts of violence. In my opinion, that's pretty much what a "clean" version of an album is. All the really dirty words are gone, but the concepts of the music are still the same.

I'm not saying that parents shouldn't pay attention to what their children are listening to, but I do think they need to make up their minds. Either your child is mature enough to listen to a certain band, or they're not.
