This is true. It is also true that the Vatican assisted fleeing Holocaust perpetrators in their escape from Europe to South America.
It is also true that Himmler had meetings with the Grand Mufti of Jerusalem.
Religion was a tool. Hitler was not religious. But the people of Germany were easily fooled into thinking their problems were the fault of the Jewish population — less than 1% of the total population of Germany at the time.
Hitler thought ‘Jewish’ was a race. We know better. That’s why we talk about anti-semitism and don’t call it racism. Jewish is not a race.
The German people contributed to, aided and assisted in Hitler’s final solution. They believed in this — some undoubtably for religious reasons. You don’t get that kind of murderous hatred from nowhere.
It was there, Hitler saw a ripe opportunity. Whether he was religious or not is beside the point.
Humans are the actors, religion was an excuse for deep, homicidal hatred that produced the Holocaust as the terrible result.
My answer is, as long as there are humans involved, hatred can be construed from the most loving of words and deeds.
