The Soviets invaded Poland, remember. Maybe you’re blanking out on that one, somehow under the impression that the Soviets “freed” Poland from the Nazis or something.
No, I’m under the impression that the Polish nation survived under Soviet oppression; something which would not have happened under Nazi oppression. Do you not know what Generalplan Ost entailed?
If you care about Polish lives you hate both Nazis and Soviets.
I do hate them both. Just not equally. The Nazis are worse, without ambiguity.
