The real problem here is that everyone seems to be overlooking the 1st Amendment rights of the students. The idea of a democracy is that all citizens need to be well-informed--well, it's hard to see how the students can be well-informed if they aren't allow to read a wide variety of books. Whether students change or commits this or the other act after reading a book depends upon the student, doesn't it? Or one could ask, how well were they brought up if they suddenly crumbled the minute they came across something different? (Of course, one can also ask if parenting on the model of brainwashing is the best way to go.) The most sensible approach is to encourage intelligence, reasonableness, knowledge, good research skills, and self-reliance in one's children, and they'll be able to handle anything they come across in a book, regardless.
I don't remember Amazon.com ever asking me what my age was.
pornography, sexual promiscuity, sexual perversion is your meaning of intellingence, reasonableness, knowledge and is considered something to have good research skills and self reliance on? What has this society come to? We don't even know the meaning of decency, morality, or common sense anymore. May God have mercy on this nation and it's people!!!!
