Anjezë Gonxhe Bojaxhiu, alias "Mother Teresa" may have helped many people, but she was still a cold-hearted bitch who happily took money-gifts from people who stole the retirements of hundreds of old folks, rubbed shoulders with the Duvalier family, and whose "Home for the Dying" was more a house of suffering because she wanted the people to be "enlightened," because she believed that suffering brought one closer to Christ.
"Keeping things in perspective" almost always seems to be code for "don't make them out to be the complete dickheads they really are." The Ancient Jews, or at the very least their leadership, were complete dickheads who thought genocide was okay because their collective hallucination told them so. Genocide is not okay. Anti-semitism was normal in Hitler's time, too, but he's the modern personification of evil for very good reasons, one of them notably being fucking attempted genocide. No one, no matter what gender, creed, time, age, or culture is ever exempt from the "genocide is not fucking okay" rule, and those that embark upon and/or order it should be treated as the living abominations they are and/or were.
