I'm not going to get into a debate, but it's interesting that the footnotes in the Wiki article for this claim has no reference to any original source material. It's all claims by other people. And the suspicion here is that one secondary source is just quoting from another secondary source. It's fundamental intellectual dishonesty.
So, I'll ask point blank: Do you, blasater1960, have any original quotes from Rushdoony to support the charge of Holocaust denial or anti-semitism?
^ R.J. Rushdoony, The Institutes of Biblical Law, (Nutley, NJ: Craig Press, 1973), pp. 586, 588, citing Vicomte Leon de Poncins, Judaism and the Vatican (London: Britons Publishing Company, 1967), p. 178. "The false witness born during World War II with respect to Germany is especially notable and revealing. The charge is repeatedly made that six million innocent Jews were slain by the Nazis, and the figure—and even larger figures—is now entrenched in the history books. Poncins, in summarizing the studies of the French Socialist, Paul Rassinier, himself a prisoner in Buchenwald, states: Rassinier reached the conclusion that the number of Jews who died after deportation is approximately 1,200,000 and this figure, he tells us, has finally been accepted as valid by the Centre Mondial de Documentation Juive Contemporaine. Likewise he notes that Paul Hilberg, in his study of the same problem, reached a total of 896,292 victims. Very many of these people died of epidemics; many were executed..."
Regarding the holocaust, that is a direct source. He was apparently at least a holocaust revisionist, not a denier in the vein of Achemadinejad. But even those revisions are sinister in my opinion. Have I run to ground the rest of the citations? no, If I have time I will out of curiosity. Hey go for it yourself! The racism (and abortion views) seem to be valid, there is a lot of info out there.
