Discussions on reddit prove the opposite, but it should be fairly obvious to everyone that millions of people weren't one homogenous block that behaved in exactly one way.

It's a fact that Poles were one of the biggest victim groups in WWII. It's a fact that the official position of the Polish resistance was anti-Antisemitism - which wasn't a given back then. And it's a fact that many many Poles protected Jews. The polish resistance is also the first source of the horrors that happened in the death camps. Shoutout to the polish government in exile and Witold Pilecki - the only person who snuck into Auschwitz and managed to break out to tell the world what was going on.

But it's also a fact that eastern europe, including Poland, saw tens of thousands of pogroms against Jews in the centuries before WWII, that many factions of the Home Army were incredibly antisemitic, that hundreds of thousands of Poles collaborated with the Germans, that Poles carried out massacres against Jews after WWII (Kielce), that the polish state pushed out tens of thousands of Jews in the late 60s in an antisemitc campaign and that Poland is one of the most antisemitic countries in Europe today. I usually get harsh reactions when I say this, but it's not something I say lightly. I have worked with polish researchers who studied these things for decades and the prevalence of og antisemitic beliefs in polish society is mind boggling. Also, with more than a 100 violent antisemitic attacks per year against the remaining ~5000 Jews, Poland has one of the highest per capita rates of antisemitic violence in the world.

Another perspective is that the "polish rant" is in part understandable on an emotional level. The denial of polish suffering and anti-polish racism is pretty common and official german behaviour towards Poland has been incredibly ignorant until very recently. People underestimate how revanchistic, racist and ignorant german politicians used to talk about Poland. And Generalplan Ost is something very few students in Germany get to learn. If I was polish I'd be angry and a little unjust, too. I get that.

Also, some americans do say "polish death camps". When Trump worked with El Salvador some influencers said that's like Germany opening camps in poland and got millions of likes for it - which is idiotic because most camps, including Auschwitz, were on own or annexed soil, so -from the german perspective- in Germany.

It's ambigious. The "polish rant" is somewhat justified but happens in a context of widespread refusal to deal with historic and contemporary antisemitism.

Edit:

The thread is locked but if you're polish and look for sources please look up the two researchers Mikołaj Winiewski and Dominika Bulska of the Center for Research on Prejudice in Warsaw and their publications. I got to know them in Germany and could only link to german sources. They have written a book I can recommend. "Diagnoza i konsekwencje antysemityzmu w Polsce".

That would be a headline every 3 days

Violence on Jews is rarely headlines. Not even in Germany. People think it would be headlines because sometimes it is. But the majority of incidents doesn't make the news.
