“Demographics can and did register the impacts of the Holocaust, let alone of the Holodomor.”
No. We can’t be sure of victims of holocaust.
If you think so, give me the number of Serbs killed by the Utase regime in extermination camp and mass execution… Or the number of Tziganes (Gypsies) killed in German’s extermination camps…

Holodomor: A Stalin’s famine specifically created for Ukraine? The fact is all Russia suffered of this one.
Still, you can’t know because no reliable statistics are available. All of them would have come either from the Tsar, or the Red Commies you don’t trust ant way…

“The Black Book of Communism”: Well, the intention is in the title and is clear: bad commies…
And from where their figures are coming from?
