Yes, I definetely don't know because:

Genocide is defined in the Convention on the Prevention and Punishment of the Crime of Genocide (CPPCG) article 2 "as any of the following acts committed with intent to destroy, in whole or in part, a national, ethnic, racial or religious group, as such:" Killing members of the group; Causing serious bodily or mental harm to members of the group; Deliberately inflicting on the group conditions of life calculated to bring about its physical destruction in whole or in part; Imposing measures intended to prevent births within the group; and forcibly transferring children of the group to another group.

The Convention (in article 2) defines genocide as "any of the following acts committed with intent to destroy, in whole or in part, a national, ethnical, racial or religious group, as such:"
(a) Killing members of the group;
(b) Causing serious bodily or mental harm to members of the group;
(c) Deliberately inflicting on the group conditions of life calculated to bring about its physical destruction in whole or in part;
(d) Imposing measures intended to prevent births within the group;
(e) Forcibly transferring children of the group to another group.


Somehow Stalin's crimes (and other communist regimes) fit both definitions.

About the rest

Batls thrived under Stalins reign and only collaborators were targeted - you mean for example at least 150 000 Lithuanians including those killed before 1941 - so they were collaborators as well ?

And the famine in Ukraine - it was enforced famine so it does count as genocide.

Poles and polish Jews were the subject of genocide as well ( from the Nazis as well - which you forgot regarding the Poles) - it cannot count as repressions because the mere fact that you were better educated, collecting stamps, knew esperanto, were a member of illegal organisation ( illegal in S.U so EVERY organisation because EVERY was illegal from Soviet point of view as created in a different country which Poland was/ is) or fullfilled one of many other frames it all meant you were eaither killed like the POWs in Katyń or deported to die in Syberia.

Moldavians were killed because they spoke Romanian - because THEY WERE ROMANIANS before June 1940 - they were supposed to forget it so it was a repression for another form of 'illegal' resistence.

M8 people were killed because they were fighting the Nazi ( like Polish underground fighters), helping Jews or doing something else communists seen as not fair - in fact they died because they were not communists themselves, or not dedicated enough or too dedicated or anything else - the resons changed from time to time and noone was safe.

Sorry but it was GENOCIDE and people are and were judged for the same or similar crimes and it was and is called genocide !
