John, Byron York, far from "sneering" at John Loftus, calls his judgement into question by reporting on his former investigations, publications, and opinions. Surely that's legitimate, and fact-based. Like this:
I first encountered (Loftus's) name in the fall of 2003, when I was working on a story about Bush hatred. I was looking at the people who claim that the Bush family got its wealth from financing the Nazis, and I discovered that one of the sacred texts of that particular worldview is a book, The Secret War Against the Jews, by the authors Mark Aarons and...John Loftus. In 1995, when the book appeared, Anti-Defamation League director Abraham Foxman, who can reasonably be counted on to speak out against people who financed the Nazis, called it "so exaggerated, so scantily documented, so overwrought and convoluted in its presentation, that Loftus and Aarons render laughable their claim to offer 'a glimpse of the world as it really is.'"
