You don’t have to look that hard to find actual displaced peoples—the way the Russian Empire burned down all of Ossetia, the way Stalin ejected most of the population of Chechnya after that, the way Crimean Tatars constituted the bulk of the population in the Crimean peninsula and then suddenly Russians and Ukrainians did for some reason—there’s plenty. (If you really want to get into the history, care to find some speakers of the North Slavic languages for me?) It’s that the example does not seem to be a good one.
The last part is so much bullshit thst it isn’t even really worth considering. (Every sentence in the whole of official Soviet history that includes the word kulak is bullshit.)
