Tsar Pogromas II may have enforced the Pale of Settlement and directed massacres of Jews at such a rate that even other European powers, themselves virulently antisemitic, were condemning Russia, but compared to the later Soviets who committed the heinous crime of opposing my cherished Bantustan settler-colony and supporting Palestinian statehood, he was a saint!
Damn, maybe he shouldn't have entered the war then 
Doesn't take too long to find her ranting about "self-hating Jews" either, because of course. The cream on top is that she's also a Shahist Iranian Gusano, living in 
no less, so this is pretty tame compared to what usually comes out of their mouths.
I'm guessing the reasoning is "the USSR invaded Poland together with Nazis, which means that all deaths in nazi Poland can be attributed to the USSR", there's no other way to make that claim. It's sad how in the past few years, everyone has been brainwashed into believing that the USSR was a nazi ally who wanted to split eastern Europe for the sake of territorial gains.
This works out great for them, because if the USSR hadn't invaded Poland, then they could still blame all those deaths on them because "they should've gone in to save those people."
They literally do it in case of Warsaw uprising, like no shit that exact claim.
What they should say to be closer to truth is: "The uprising was purposefully started in the precise moment Red Army was unable to help, because it was aimed politically against USSR, and the Polish partisans we accuse of being Kremlin puppets still participated in it, but now we will cry and whine why people we and the organizers of uprising thought as enemies didn't helped. Also they did helped as much as they could, but we ignore it"
They refuse to acknowledge the historical fact of the collective security policy adoptedd by the USSR in the 30s which sought to create mutual defence agreements with Poland, England and France, and which were systematically refused by these countries. It's simply a revisionist rewriting of history.
So they advocate for USSR invading Poland before and taking entire country or what? USSR evacuated Jews from former Polish territory so that's historically the only method that would really saved the Polish Jews.
(of course i know they aren't, they just have less than zero knowledge about history)
They advocate for USSR selflessly sending all their troops to fight Nazism in Poland, after Poland had rejected for the entire decade of the 30s all the proposals for mutual defense agreements by the USSR, as France and England did. As you say, they just don't know their history. They refuse to acknowledge the 10 years of attempts of mutual defense agreements by the USSR with France, Poland and England, and what's more, the modern foundational myth of Poland is based on independence from a supposedly tyrannical and consistently oppressive Russia that is continuous over time regardless of the immense changes in political systems over the past century in Russia. It's simply impossible to argue against that with most Polish people.
Yes, our history got revisioned and rewritten after 1989
