Ann Coulter?

I wrote a paper about banning and not banning Ann Coulter books. The main point was concerning Free Speech. I got a letter written to the editor that Ann's books should not be banned and now I have to persuade them that they should be banned. I need to know of a group or a person who feels that her books should not be banned and they need to have very strong reasons why, not just because they think she is a bigot! I also included in my paper how some rappers, radio personalities, athletes, and, actors have been punished for there misuse of the Freedom of Speech. If anyone has any ideas please answer my question. Thanks!
