I provided that ukrainians comited genocide on poles in Galicia. Lwów is part of Galicia. So, Ukrainians killed Poles in Lwów. So, I gave you evidence.

And about that, population exchange... most of poles who lived in "modernday ukraine" were killed, so the soviets didn't have much to do.

Yes, Poles also killed ukrainians, but look at the scale! Beside, we only did it for revenge. The ukrainians were the one who started that hell. And don't forget, about how horrible that crimes were. OUN and UPA burned people alive, brutally raped women, and they literally impaled children. Volhynia massacre makes holocaust look like a fucking joke.

Did you just compare the most brutal genocide in human history to mass deportation? ARE YOU FUCKING KIDDING ME?! OPERATION VISTULA WASN'T EVEN HALF AS BAD AS UKRAINIAN WAR CRIMES! Actually, I could even say, that deportation was the best thing that happend to them. That subhumans deserved much worse.
