In Fahrenheit 451 how have books become censored?

All books were banned. The only thing allowed was comics books, 3D sex magazines and scripts for the people in the parlor. Books were banned because they can be viewed in different ways and cause people to think differently. The government didnt want this because they believed it brought sadness.

You may say, "But isn't a script like a book?"

The answer is no, because reading a script is just basically being told to do something.

You are being controlled by the TV unknowingly, which is what the government wants in Fahrenheit 451. The government wants to control the people completely, but have them think they are making their own decisions. They don't want anybody to think any differently than anyone else, thus people don't even have imaginations.
