'A Fallacy Files Christmas'

Back in 1897 an 8-year old child called Virginia wrote a letter to the editor of The New York Sun asking whether Santa Claus was real. She had been told by some of her friends that Santa didn't exist. Her father told her to write to The New York Sun because, according to him, if it appeared in the newspaper then it must be true. She wrote to the paper and received a reply, which was published, arguing that Santa Clause was, indeed, real. There was also a follow-up editorial critiquing the first one. You can read both of the letters here: Fallacy Watch: A Fallacy Files Christmas. There are also some links to the fallacies that appear in the letters.
