I went through a sanctification process, maybe 10-12 years ago now, where I realized that some of the music, TV, and books I was allowing into my life were not growing me in the direction that the Holy Spirit wanted me to grow. And that they created in me a desire to do things I knew were sinful (for me). So I threw out a bunch of stuff.
Now what I didn’t do was invite people over and tell them how I had thrown out a bunch of stuff that was evil and they should, too. Because it was personal, and all of the stuff I threw out wasn’t sinful in and of itself; it was my own mind/heart/soul that was doing the sinning (or the not growing in some cases).
Now there might be some stuff that “should” be destroyed: child pornography comes to mind. I don’t see how that could benefit anyone. But even destroying that blurs the line and makes it easy to call for the banning or destruction of other art that is NOT pornography.
Trying to force others not to read something by burning it, in my study of history, has never seemed to really change the hearts of the people involved and often resulted in the destruction of things that really were beautiful and good and true. So I guess the short answer is no, I don’t think books or music should necessarily be destroyed because of their content. But we all have the responsibility of listening to the Holy Spirit’s prompting in our lives regarding what we personally choose to imbibe.
