A good part of the ethnic Russians fight on Ukrainian side. If you weren’t aware, for a lomg time Russian was the official language of the Azov Battalion.
But you go on believing Russian lies even after Prigozhin has admitted openly that all the stories were a lie.
As for Ukrainians calling all Russians orcs I cannot blame them after the horrors of Bucha, Olevnika, Mariupol, the endless targeting of infrastructure, all while the general Russian population not only doesn’t care but openly support it.
But you would have cried foul over Poles cursing Germans in 1945 too pointing out innocent Germans did possibly exist, so I don’t care too much.
