No I'm not. Big difference between cultural Catholics and practicing Catholics just as there's a big difference between cultural Protestants and practicing Protestants. Furthermore, the Catholics are headquartered out of Vatican City which is sovereign territory.
I refer to almost entirely Catholic, fascist Italy, an Axis power, allied with Hitler.
Are you seriously claiming that every Catholic who supported the fascist regime of Mussolini, a Catholic, was somehow not really Catholic?
How many Jews were there in Italy at that time, and how were they treated? Protestants weren’t even treated especially well, what few there were. I know Waldensians didn’t get full religious rights in Italy until 1984.
