I have a feeling no one read the Wikipedia page...
As for OP's question, it's because nothing turns on people lost in power than more power. People love to be right and argue, some more than others, shown quite well with all of the controversies that occur in the world, whether it be as petty as sexism in video games, or as the events that lead to many major conflicts throughout history.
Now the link below the page on actually banned books by governments is something that would apply here.
This does not mean that they were banned. This means that they were highly contested as study material in school because of reasons that may or may not have made sense. I've read a good chunk of titles on that list, and the reason for even considering them to be banned baffles me.Taken from Wikipedia itself said:"This list of most commonly challenged books in the United States lists some of the books challenged from 1990 to 1999 in the United States.[1]
In the United States, many books have been challenged by a variety of groups and agencies to prevent a particular work from being read by the general public.[citation needed] In recent years, it has become more common for those challenging the availability of a book to do so on a local level, targeting public libraries and school libraries. Many communities have a formal process by which a citizen may challenge the public availability of a work."
