First of all let's remember that restrition of movement is the norm in any armed conflict.
Having said that, in order to qualify as genocide the number of forced relocations of Ukrainians to Russia and Russians to Ukraine would have to be in the order of hundreds of thousands, at the very least.
Where are all those ukrainians being held in Russia against their will? Not even a totalitarian state like North Korea would be able to completely hide so many people from view for so long in the age of cell phones let alone a mere autocracy like Russia.
Nobody can't find a single Ukrainian family forced to live in Russia, let alone hundreds of thousands, because the whole story is total garbage, that's why...
And just for the sake of the argument... Even if the story were true it would still not qualify as genocide. Ukrainians and Russians are all east slavs, two extremelly close ethnic groups. The idea that mass immigration of Russians to Ukraine, forced or not, would represent any kind of genocide is as absurd as the idea that mass immigration of anglo canadians to the US would lead to the genocide of anglo americans.
If you want to see a real genocide in action look no further than the millions of non-white immigrants who arrive in America every decade and the massive indoctrination campaign of the american youth with pro miscegenation propaganda.
You and JohnDB accuse Russia of an imaginary genocide that only exists inside your heads and sweep under the carpet, ignore, justify and rationalize the real genocide that's happening in front of you, in your country and targeting your own ethnic group.
