Double genocide is a literal Nazi talking point created, ironically enough, a Canadian Nazi.
The Ukrainian famine wasn’t intentional (many parts of Europe and even other parts of the USSR suffered equal if not greater famines). This is agreed upon by any serious historian who studied the USSR after its dissolution and the archives were opened.
The Waffen SS and other Ukrainian fascists organisations literally carried out pogroms agains Jews, Roma and Polish people. So your comparison is really disgusting to be honest. The USSR and the Ukrainian Red Army liberated many minorities across Easter Europe from fascists and Nazis.
It’s absolutely a historical fact that the USSR and the Red Armies were the most directly responsible for the Nazi defeat in WW2, the liberation of Jews, Roma and other minorities. And honestly, saving the fucking world.
You can hate Stalin, but it’s just undeniable he was absolutely instrumental in defeating Hitler.
If you resent the role of the USSR during WW2, and “see why someone would join the Waffen SS to fight the Russian invaders”, all that tells me is that you are a fucking Nazi.
