To the ignoramuses who are trying to say The Hoax of the Twentieth Century (
http://vho.org/GB/Books/thottc/) hasn't been banned you are dead wrong. This book is banned in any country that has laws against holocaust denial. You don't have to take my word for it. Simply contact the consulates of any of the countries listed. For instance, call-write-email your nearest German embassy telling them you wish to send a friend in Germany a copy of a book called The Hoax of the Twentieth Century and is it legal there as you have heard they have laws against holocaust denial. This book has been banned in Germany for decades now.
It's your claim that the book has been banned in various nations, so it's up to you to furnish the proof of that claim if requested. Why should I do your work for you? I see no reason why I should take your claims as true without supporting evidence.
Now, that said, I went ahead and looked into your claim that the book is banned in Canada. The
Freedom to Read web site maintains a PDF file listing books and magazines that have been challenged or banned in some way (typically at the local level, i.e. a school library, and not by an act of the provincial or federal government). It lists, by decade, each book or magazine and the circumstances and outcome of its case.
The only entry I can find on the book in question is on page 26 of the
PDF file. It says the following:
Freedom to Read—Challenged Books and Magazines List said:
1980-89
Butz, Arthur. The Hoax of the Twentieth Century.
1984—This book was seized from the library of the University of Calgary by RCMP officers acting under the authority of the Customs Tariff Act.
Cause of objection—Classified as “hate literature.”
Update—The book was put back on the university’s library shelves because of a technicality—Customs officers’ prohibition of the book came after the book had entered the country.
1995—A copy of the book was seized by the RCMP from a public library in Didsbury (AB). Before the librarian could respond to the seizure, the book was shredded—because the RCMP said it was prohibited.
And that's the whole extent of the book's mention by a group which dedicates itself to following such affairs (as the PDF file attests). It would seem it's not a particularly popular book, or it is resting quietly unnoticed on the shelves of other libraries.
And, indeed, my latter comment appears to be correct. Using the
University of Toronto Library web site to run a search for the author, Mr. Butz, I was provided with three search results. There are currently three copies of the book in two different libraries of the University of Toronto. It may well be available in other libraries; I didn't check because no more effort was needed to refute your claim.
Conclusion: your claim that the book is banned in Canada is incorrect.
I'll leave it to the citizens of the other nations you listed to examine the book's status in their particular country.
