The invaders in the temporarily occupied territories create lists of disloyal residents with further pressure on them.
In particular, educational institutions have been advised not to take children from “disloyal families” on excursions or other entertainment events. In particular, to put pressure on them to force children to join Kremlin movements.
Thus, in fact, Russians are segregating Ukrainians in the TOT so that they feel unwelcome at home and either assimilate or leave. Such actions are a continuation of the policy of genocide and the destruction of an entire generation of Ukrainians.
You can stop the policy of the Russian invaders and their collaborators by publicizing their crimes and demanding their international prosecution. You can also participate in rallies in support of Ukraine or donate to the Armed Forces of Ukraine.
