I don't believe in censorship, but I do think that labeling things like movies is very helpful.
It's kind of like labeling the contents of food. For example, you know your kid can't eat peanuts, and you don't let them. However, you buy some cake mix and it isn't labeled that it has peanut and your kid dies because the label is wrong.
Of course, that is extreme.
I think shows need to be labeled so that parents know if there are cuss words, sexual themes, violence, etc. Then the parents are well-informed and can make an educated decision about the show.
Yes, I think you have something here. It seems to be working with movie ratings perhaps it could work for TV. I like the idea of giving the parents the final say. :0)
