What the fuck are you even talking about? Russia is throwing thousands of „working class“ lives away, since it wants to expand its territory in aggressive moves since decades. They are forcing Ukraine to defend itself and yes, those are also working class people.
So you, as a good socialist, are probably on the barricades because of this unprovoked attack on the Ukrainian working class. How are you fighting to defend them from getting killed? Please don’t answer something in the likes of „Ukraine should give up“ because then everyone would only see that you are actually advocating the Murder of the Ukrainian people.
