I think the original point is that Poles or Germans of Polish descent who survived the war have been forcefully Germanized - as in, refused the right to organize Polish schools etc. not in the modern days, but in the post war era (45-89). There is a big group of these people (e.g. in Ruhr area) but it's really hard for me to tell (and I'm a Polish migrant living in Germany myself) if that was the case, or it was the idea that Poles/Germans of Polish descent after the war were afraid of ethnical Germans and as a result, repressed the manifest of national identity/ethnicity. It definitely was (and still is) the case for Jewish survivors of the 1939-1945 regime, but the anti-Jewish and anti-Polish sentiments didn't end from day to day and it's extremely hard to narrow down what was the cause of it.
