The deaths of a few dozen people in a building fire at the end of a running street battle in which Ukrainians are killed by gunfire from some of the people in the building = genocide? The deliberate mass starvation of millions of Ukrainians by Russians during the Holodomor was a genocide. The mass killings of millions of civilians (Poles and Ukrainians and 1/2 of the world's Jews) by Germans was a genocide. The casualties of a running street battle are not a genocide.
So, how exactly "Russians" deliberately starvated millions of Ukraininans (of whom many were actually ethnicRussians)?
You say: "The casualties of a running street battle are not a genocide.".
Well, US-NATO "justice" says otherwise. The casualties of Muslim fighters in Srebrenica were declared "Genocide" by U.S. sponsored ICTY kangaroo court.
If several thousand KIA combattants are genocide, several hundred unarmed civilians are genocide as well.
You can not have it both ways.
