Collaborators were punished because they were traitors and everyone seen and sees them like such.
Below is a link to a Wikipedia where you can learn more:

I hope you will understand how offensive and false your comment is.
> Especially in the early weeks of the German offensive, many thousands of Jews were murdered by members of local communities in the western parts of the previously Soviet zone, such as the Baltic countries, eastern Poland, and western Ukraine.
I am absolutely not trying to paint a complex situation in black and white. The article you linked to also points out how many non-jewish poles were killed, how many non-jewish poles helped jewish poles at great risk to themselves, etc. but the idea that you can “other” collaborator poles out of being poles is denying the reality.
> The bill was proposed by the country’s ruling Law and Justice party (PiS) and calls for up to three years in prison or a fine for accusing the Polish state or people of involvement or responsibility for the Nazi occupation during World War II
The law has since passed, tho it was later amended to remove the prison time portion.
Now I am not a lawyer, nor am I polish, so I don't know what the situation is on the ground - but I believe the law makes repeating much of the contents of this wikipedia page illegal https://en.wikipedia.org/wiki/Collaboration_in_German-occupi...
