I know nothing about Poles in SS.
And there we have a perfect example of an inconvenient part of Polish history: there were indeed Poles in the SS, thousands of them (if we make the assumption that one in fifty of the Poles who were captured by the Western allies while fighting for Germany were SS (very much an under-estimation of the percentage of German forces which were SS in 1944/5), there must have been at least two thousand). But instead of this history being examined, it is swept away and denied.
Given example of an individual recognized by the Interned sources (both German and Polish)as an Belorussian.
The man in question was born in Poland to a Polish mother (Polish in terms of ethnicity and citizenship) and an unknown father (thought by most to be Jewish), he self-identified as Polish both before and after the war. But to Polish sources he is Belorussian. What was I saying about denial?
Attempt to recruit from Highlanders drew few volunteers but came to nothing.
A few hundred actually, but that fact is also inconvenient, let's sweep it away.
Poland only political prison could be hardly called concentration camp
The term "concentration camp" was used by contemporary media to describe the camps in question. But it is easier to simply deny that fact.
its existence is no secrets to any-one, Poles are learning about it in school.
Clearly you were not paying attention: you say "Poland only political prison" and then "its ... is ... it", so to you there is apparently only one camp. The fact is that there were several. But it is easier to deny again.
many Germans fled in panic as RED ARMY entered German territory
And many stayed, some of whom were then put into Polish concentration camps but of course that is just another inconvenient part of Polish history, let's deny it.
Treatment of minorities in Poland before WWII wasn't that bad,
Sure, all you did was ban their language, close their schools, close their churches, close their libraries, close their reading rooms, ban their organisations and send anybody who objected too loudly to a concentration camp. None of that is bad!
As for construct State-sponsored anti-semitism don't know what author had in mind, but if my guess is correct I should point out that USA had the same laws for much longer than Poland.
Really? Could you be so kind as to point out the US law which said that Jews could only sit on certain benches in universities? Or to the US medical association or bar association banning Jews from joining?
Shall I go on?[
Yes please do give us more examples of how some Poles think that the inconvenient parts of Polish history should be dealt with.
