>easily find evidence that Lenin and others sought to discipline kulaks, but nowhere are the Holodomor's famines mentioned there.

that is what i was talking about - disciplining kulaks, successful peasants, which basically meant destroying significant part of the peasant population there. And if you look at the map i linked - those regions had mostly Ukrainian speaking peasant population.

You probably have different than bolshevik's notion what "disciplining" is. Bolsheviks were outright genociding whole social stratas (and kulaks were one of such a strata) because bolsheviks saw no place for those people in the supposedly beautiful future the bolsheviks were supposedly building. And just for an example - you probably not aware how bolsheviks used chemical weapons against peasant revolt in Tambov region.
