Are you for real?
Yes, I am for real. Weather this grandpa did anything wrong, or If he is Polish, is totally off-topic and has nothing to do with this law. Just like "hate speech" law doesn't make it illegal to claim that Bernard Madoff is a stinking thief or report that some homo committed a crime. A BBC person got several facts and had to put it into words within 15 minutes and that's it.
being just like the Swedes and the Danes
Definitely not being like Swedes, who supplied and traded with Germans aka "Nazis" and definitely not like Danes, who capitulated after losing 5 soldiers and were allowed to keep their democratically elected government during their "occupation".
If you were in a Ghetto or KZ collaborating with the Nazis might be one of the few ways you thought you could survive.
They were millions of Jews outside of occupied territories. Some were not giving a damn sitting in NY, others were shooting at British in the Palestine, while those in the Soviet Union were loyally serving (often in the red army and NKVD) the Adolf's ally. When you Nazis were building Auschwitz, they were busy putting Poles, Balts etc. into trains to Siberia.
But of course, as the search for each and every case when Stanisław was denouncing Mosh to "Nazis" became like a sport for some people, any mention of Moshe sending Stanisław to Gulag is "anti-semitic". Jews as a whole don't really have a good record in regard to WW2. One of (several) reasons of their whole idiotic approach to the subject, is to hide it all behind "Holocaust".
