since when were the Jews "perpetrators" of anything during the period of which we're talking other than of trying to survive against nearly insurmountable odds?
Like when they massacred thousands of innocent Persians and to this day celebrate the massacre via Purim?
The Jews were kicked out of over 100 different kingdoms, states, principalities, towns, etc. all over Europe. Poland was their last resort because everyone else got sick of their usury and banished them - including many Polish cities at one point or other. They begged Poland's king to take them, to which he obliged and passed laws banning forced baptism under punishment of death. But of course it's the 100 different European countries faults. The Jews and Poles lived together peacefully until after WW2 when they felt the Poles didn't do enough to protect them from the Nazi invasion and afterward sided with the Russians and imposed a climate of torture, extortion, repression, etc. via zydokomonu after WW2.
Berlin's Holocaust Center on Potsdamer Platz is already one too many
It is. The supposed 6 million have already been honored enough - they've gotten tons of money, books, memorials, their own freaken country as a result, not to mention have been bullying Palestians, committing massacres, bombing unis and hospitals, setting up illegal settlements, etc. ever since. There are more Holocaust claims for monetary compensation than there are victims and that's a fact. Poland, Russia, Germany, France, etc. have not had nearly the same reparations and treatment that the Jews had despite having the same or even far higher victim counts. Israel has had more UN resolutions against it than Cuba and North Korea combined for all the crimes they've committed in Lebanon, Palestine, etc. They've even murdered American sailors. When Obama gave Israel some $10 billion in a very typical response they were upset at their government because they felt they could've gotten more money from the Americans. Time to focus more on the 70+ million others who died during WW2.
