Before 2014 in Ukraine's capitol most people spoke russian. There was no "ethnic cleaning" or punishment. Russians were not "in their own country", they were in Ukraine.
Speaking of ethnic cleaning, how many Ukraine schools or Ukraine churches remain in russian occupied areas?
None
There are Ukranian native speakers in Russia.
From Grok.
Ukrainian-Speaking Communities: Ethnic Ukrainians in Russia, estimated at around 1.9 million (2010 Russian census), are concentrated in regions like Tyumen, Moscow, and Krasnodar Krai. However, the actual number of Ukrainian speakers is likely lower due to assimilation and Russification. Many ethnic Ukrainians in Russia speak Russian as their primary language, a result of historical policies and social pressures. In rural areas near Ukraine, such as Kursk or Voronezh, some communities may use Ukrainian or Surzhyk (a Ukrainian-Russian pidgin), but this is limited and lacks institutional support.
Unlike the Ukraine.
