More evidence of the mass extermination of eastern Germans:
The Open Wound by Samuel D Sinner
The Expulsion by Erik Edelstamm
There should be a memorial for these people. OK, so some of them had settled in Eastern Europe on the basis of Hitler's Lebensraum policy; but many of them had been there since the Austro-Hungarian Empire and even the Middle Ages. East Prussia, Pomerania and Silesia had been German areas since the 13th century. There is official denial that this even happened, but there are eyewitness accounts and documents.
Apparently it's not politically correct to mention this particular genocide, as it's often used as an argument by neo-Nazi revisionists and deniers of the Holocaust. However, the way I see it is, genocide is genocide is genocide. Just because these people happened to be Germans, doesn't mean they were worth less than other people. Most of them were civilians - farmers and artisans.
There needs to be a process like the Truth and Reconciliation Commission in South Africa, which dealt with both black and white people who had committed murder during the apartheid era, even though the apartheid system was set up by whites. The Czechs have apologised and put up a memorial in 1990, but the rest of Eastern Europe has yet to follow suit. Haven't they heard of the saying "Two wrongs don't make a right"?
