yes thats true, i can say Asiatic satanists started to do it even early in the eastern Belarus - Ukraine for instance , and not just Poles, catholic, lutheran Belarusians too . then 1929 , 32, 36-38 etc pure genocide
The biggest targets of Stalin, were especially in disproportionate terms the Ukrainians, in the Holodomor, and over 20% of GULAG victims were also Ukrainians.
But, Poles were probably a close second.
Besides the Holodomor, the Polish Operation of the NKVD 1937 - 1938, was probably the biggest ethnic operation Stalin had.
However, Volga Germans, and Islamic Tatars were forced off the land in mass deportations.
Yes, many other groups were brutalized by Stalin, Finns, Baltic-Germans, Belarussians, Romanians etc. etc.
