I am currently unmarried, so I don't have any children, but when I was younger my mother was very careful about what she let me read. She always made sure to go through books that weren't in our particular age group first, and if there was something she found objectionable she would just tell us not to read that part. My mother was very good in the "censoring" area. Sometime parents can be a bit overprotective in these areas for whatever reason, but my mother never did it in a way that made us feel she was trying to control us. She just had a lot of faith in us to respect her wishes to keep us away from things that she felt we didn't need to subject ourselves to yet. When we were older she would let us choose our own books, trusting that from all she had taught us, we would then "censor" the material ourselves, and discuss whatever sort of "content" we came across in the book. I hope to emulate this quality when I have my own children, because I feel it really helped me a lot. I am still very careful about what I read. It is another reason why I have a content rating, for parents, or young adult/adults like me who are also careful.
