@JapanProf@DropBear@oatmeal@palestine@israel the only possible explanation that occurs to me is that because their education system puts so much emphasis on the abuses by the nazis and other populations against the Jews that they have unintentionally normalised such behaviour and desensitised the Jewish population to horrific levels of murder and violence.
People brought up to believe violence and killing and cruelty is normal will use violence, killing and inhumane cruelty themselves.
