 "If left alone it will read "Germans are murderers who only want to murder Poles." I am sorry if you feel that way but what are you proposing ? The history of Germany has many cases of atrocities against Poles. Nobody is claiming what you wrote, but that doesn't mean we shouldn't write about history or delete those facts.Is that what you are proposing ? Anyway your opinion isn't true since before vandalisation there sections of persecution of Poles in other countries.
