Nah, its ok, I only mentioned the ukranians because I didn't know the full span of the nations affected by it. I learned of the holodomor through Russian and Ukrainian sources.
On the cossacks, while their status as a nation is often put into question (mostly due to the fact that nobody bothered to study them before they became relevant in major conflicts), cossacks have, you know, actual culture, with folklore, myths and customs, and were very much a significant nation during and before the times of the polish commonwealth. It is true, however, that the people we know today as "cossacks" were actualy made out of several different east slavic peoples that became more united during the second millenium AD, and were often exploited as serfs, who ran away and joined up, creating armed groups.
We just have very few records of cossacks before the 16th century, probably because nobody actualy cared to take note of them until they got their hands on firearms and started fighting the stablished powers of the time. This is mostly why they're always referenced by russian and ukranian sources as "warriors" and "men of adventure".
Genocide is the intentional and systematic destruction of national, political, cultural or racial groups, regardless of the reason or the method used. While the deliberate nature of the holodomor is often questioned, everyone pretty much agrees that Stalin was willing to industrialize the soviet union at any cost, and it wouldn't be the fist time the soviet union would cause the deaths of huge numbers of people for the sake of creating a completely united political entity under the communist party's control.
Altough ye, this thread might not be the best place to talk about this :v
