Absolutely not.

/u/kieslowskifan covered points in "Did Poland take any aggressive action towards Germany and the German people that instigated the German invasion?" , touching on Polish treatment of local Germans and Hitler's statements months before the war.

It's also addressed in "Did Hitler really invade Poland to liberate ethnic Germans in the Danzig corridor from Polish slaughter, rape, mutilation, etc?" by /u/vonadler .

Based on other replies, /u/Georgy_K_Zhukov may also have points to add.

I have not found articles pertaining to the "communist" adjective. crrpit replied to "How were communists and any Communist Party treated in the Second Polish Republic (1918–1939)?" .
