That's odd, because I just did a search, and the first hit on "traditional enemies of truth" is this JREF thread, and then 2 and 3 are from Stormfront, talking about David Irving, 6 is an article in the Guardian on David Irving, and 7, 8, and 10 refer to the term as typically used by Holocaust deniers.( #10 was co-written by Michael Shermer).
Well, "for the record", Irving often uses the term to refer to jews and this is found on the web in numerous places, but I had in mind in particular Irving's use of the term in his libel suit against Lipstadt, described in that excellent book(*), "Lying About Hitler" by Evans.
In one of those ironic "operation foot bazooka" moves that characterized Irving's lawsuit, he gave the court the list of the "traditional enemies of truth" from his own website--as evidence that he is NOT an antisemite, since there were non-jewish organizations and people on that list. But as the defense attorney, QC Richard Rampton, noted, of all the dozens of "traditional enemies of truth" organizations Irving's list, every single one (apart from the Australian and Canadian governments, which, no doubt, Irving is sure are controlled by the jews anyway) was, in fact, a jewish organization.
(*)For the internet generation: Google "book" if you don't know what a book is. It's really amazing--imaging 100, 200, and even more web pages all put together in one compact place, which you can browse offline!
