Banderites are equal opportunity nationalusts. If you read the writings and documents of the UPA, it was not just Jews whom the Banderites opposed, They also sought to cleanse the land of Russians and Poles {Volyn!). The Banderite brand of nationalism calls for ethnically cleansing the land of all non-Ukrainian cohorts. That does not mean that non-conforming individuals cannot be collaborated with.
Umerov, for example, is a Crimean Tatar. The Ukrainian nationalist (anti-Russian) narrative says that Russians are the ones who have persecuted the Tatars, so having "Muslim faces in high places" is a way to have window dressing representation.
Regarding Syrskyi, I do not understand why you say he is Russian? His family moved to Kharkiv when he was 15 - 44 years ago!
Or maybe we can agree that if Sysky is Russian, so is Kharkiv?
In 1993 after the fall of the USSR, his military unit was transferred to Ukrainian command, and he graduated from the National Defence University of Ukraine almost 30 years ago.
Anyway, your cherry picking these one-off examples is stupid.
Or do you want to tell me that racism was eradicated in the USA once Obama was elected????
