In an effort to keep this on the rails before it goes off, I must state that the expelling of 15 million ethnic Germans between 1945-48 is an historical fact.

While the numbers killed will be debated for years, many Poles, Czechs, Romanians, Hungarians (and others) took the opportunity to exact revenge for 6 years of war and occupation on these German civilians.All men are capable of evil deeds, and in recent years this mass expulsion of Germans from ancestral homelands is considered ethnic cleansing.

If further reading is required, there are many books on the market by a myriad of scholars on this subject..if you have not read about this subject before, you will be surprised at the sheer scale of the movement, and the violence.
