In some contexts I think it is fair to generalize about groups “hating” each other... Palestinians & Israelis... the Sinhalese & the Tamils... N. Irish Catholics & Protestants. And so on.
A pogrom isn’t exactly what you would call a political conflict.
The Holocaust against Jews (and Gypsies) was quite distinct from whatever wars between Eastern European nationalities or nations that you are referring to.
I don’t see what point you are trying to make.
That's not entirely fair, since the war and the Germans changed the environment radically, but you do find people taking political conflicts before the war as a prelude to the Holocaust, rather than something that under other circumstances would have resolved over time.
I was also pointing out that violence against Jewish escapees who took up with partisans was often a result of political conflict between various factions, rather than ethnic violence.
I don't think you can draw quite as emphatic a line as you'd like. A guerrilla outfit that did kill Jews might have other victims as well, and many of them also quite as innocent.
