There's 3.5 million people living in the Russia-occupied territories of Ukraine now. The Wikipedia entry about them even lists "forced Russification" as one of the abuses they suffer: "Ukrainians have been coerced into taking Russian passports and becoming Russian citizens". Now, as bad as this is, being forced to become a regular citizen of the occupying state is a far cry from being deported and murdered by that state. Nazi Germany wasn't giving German citizenship to Poles and Jews in occupied territories; Israel is not giving Israeli citizenship to Palestinians in occupied territories. Do you see the difference?

Putin himself has famously claimed that Russians and Ukrainians are the same people: this is the very opposite of the ideological premise to justify a genocide.
