No, FRiend, shame on you for jumping to unwarranted conclusions.
Yes, I'll agree that Olog-hai's link criticizing Rosen's book is interesting food for thought.
But I do not buy all of it's arguments, am certain its authors are also biased, likely unreliable, and most important, they fail to address the major theme of Rosen's book, namely, that President Roosevelt deserves more credit for his efforts to save Europe's Jews than he us normally granted.
Instead, they engage in endless nitpicking of academic points of little or no interest outside their own hallowed-halls.
So, shame of you, FRiend, if you also fail to "get" the most cogent point here.
