Holocaust Deniers and 9-11 Deniers
Go together like peas and carrots. Stephen Lemons covers the denial of Holocaust Denial by Eric D. Williams and Jim (Man from) Marrs:
"One unnecessary death IS a holocaust"? Williams invents his own definition for the word Holocaust, and insists on it as the basis for reality -- his reality. Thing is, his book denies the reality of the charnel house of Auschwitz in specific and the mass murder of European Jewry during WWII in general. Check out some of the whoppers he propagates.
Williams repeats all the standard tropes, like the claim that there was a swimming pool at Auschwitz. There was, but it was for the guards.
