That's a rather pompous assertion. But to do the subject-matter credit, Hogan's collaborative refutation of the ZOA article can be found here:Anatomy of a Whitewash: A Critical Examination and Refutation of the Historical Revisionist "Deir Yassin: History of A Lie," Issued By the Zionist Organization of America (Mar. 8, 1998)
It can also be found in several other Arab Islamic sites which like to whitewash their own involvement in precipitating the hell of war.
Couple of points about the alleged refutation of the ZOA article.
Hogan and McGowan do not refute the figure of dead arrived at by the ZOA article nor, it appears the original source for the false and bloated figures (an Arab). Secondly, while they complain about the source material (the very reputable Uri Milstein largely), and assert the lack of other sources, in point of fact Milstein bases his work on numerous interviews and other primary source information. It turns out their criticism is vacuous. As the ZOA article quotes from Benny Morris (by the way a New Historian and anti-Zionist),"Benny Morris, dean of Israel's leftwing "new historians," has written that Milstein's study "will most likely turn out to be the definitive military history of the 1948 war...No one is likely to surpass the sheer breadth, depth, and scope of this work...Israeli military history has now been pulled up to a new, higher and refreshing plane." (Morris, "'Pre-History' vs. 'History', Jerusalem Post, 9 May 1989, p.40). "
By the way, you will note that in the Hogan article you gave the link source to, Hogan himself relies on Milstein numerous times. Arguably a case of picking and choosing the material which lends itself to Hogan's thesis and rejecting the contrary material.
Finally, the "demanding truth" assertion is only accomplished by having MORE than ONE position advanced. That is exactly the point of the criticism in this article and the above postings. To that end your criticism is itself self-contradictory.
