Query: Anti-Catholic bias

Despite the trappings of scholarship, the book is unbalanced. It systematically ignores or downplays the evidence of the Catholic Church's opposition to Nazism. Mit Brennender Sorge, Pius XII's courageous encyclical against Nazism in 1937, is dismissed as a fluke. In fact, it was written with the full support of the German bishops and its publication triggered a bitter persecution of German Catholics. There is little here on the destruction of Catholic schools, the show trials of clergy, the destruction of the Catholic press, the persecution of the religious orders. On the other hand, every sign of Catholic sympathy for Hitler is magnified out of proportion.The result is an anti-Catholic cartoon.
