We're trying to raise them to be able to make sound judgments on their own. It's difficult being parents, it must be twice as difficult being a single parent. Parents need all the help they can get. The industry must continue to help with warning labels, the stores must post them prominently and assist ignorant parents with hip kids. But the government has to stay out of the way.
Censorship is a job the government is decidedly unsuited for.
We learned that in the 1950s. There's a galaxy of beautiful music kids and parents can choose from and talk about. In our family, we all agree on the Beatles and Fleetwood Mac. After a lifetime of hating country music, my daughters played the Dixie Chicks and I now admit to liking them because I love the song where Earl has to die. When our kids were taking piano lessons, I played Bud Powell, Keith Jarret, and Mozart's piano concertos for them.
