re: No it is not written
The only thing that is written is Palin asked the Liberian how you would feel about banning some books because some citizens thought some books had inappropriate language in them. The Liberian rightly explained to Palin it would be unacceptable.
Nowhere in your articles, nor do any of the Palin critics say Palin asked the Liberian to ban any books.
The city of Wasilla has issued a pdf (see City Documents - Recently Requested then Banned or Censured Books Response) regarding this mess and if you will notice during the time Palin was mayor no books were even discussed about censorship or banning.
The chicken is not only stuffed with the wrong ingredients, but cooked.
