Prager has a very Judeo-centric view of both history and religion, which can be a blind spot for him.
For instance, he has said that "Jews are not the only victims of revolutions, but they are always the first victims." The "Jews as canary in the coalmine" theory.
Well, no. I emailed him, saying that in the French Revolution, only Catholic clergy were persecuted. Jews were emancipated. And in the Russian Revolution, the Bolsheviks first targeted Christian Orthodox clergy, nuns, and believers. Only later did they turn on other religions.
