I agree with yekke2’s response. Sorry, Utah, but I don’t think your reply changes the validity of his points.
I’ll just add that the fact that people you know who had library access “turned out fine” is not a very good argument, on many levels. For one, even granting that they wouldn’t have turned out even finer had they not gone to the library (which I don’t), it’s still not okay for kids to read what they shouldn’t.
