Also, not one single Pole served as a guard in the Death Camps, not one. There were plenty of Ukrainian guards.
Yes, some Poles were anti-semitic, and it was confounded by the sheer number of Jews in Poland at the time.
But I would dare say, they were no worse than the French nor the Dutch. By the way, the Netherlands had the highest volunteer rate for the Waffen-SS of any other country. And who betrayed Anne Frank and her family, most likely a Dutch person.
The French still are, Poland not so much.
