There probably were, I just imagine it's an insanely small percentage. Especially during barbarossa. Similar to how the right wing factions fought alongside communists to resist Japanese occupation in China and Korea. Like of course there's going to be some small groups, but strategically any sane group would've picked a side (and any non-fascist one would've sided with the Soviets).

It's also such an insane proposition to be partisans fighting both sides without external support that I doubt they have many survivors or ancestors anyway.

I doubt WW2 Ukraine had very many of that kind of confused American libertarian.

Even if there were, if you're actively fighting the government while they are busy fighting an invading force, you're doing the work of a fifth columnist for that force, regardless of if you actually support them. So if an "enlightened centrist" Ukrainian partisan did exist, their effect during the war would be indistinguishable from those actively supporting the nazis.

The UA partisans who fought against the Nazis were pissed off the Nazis wouldn't let them have their own genocidal fascist ethnostate. It wasn't some kind of noble rebellion. They were just so fucking stupid and high on racial superiority they thought the Reich would let them make their own Ukrainian Nazi country, and when the Nazis very obviously didn't do that a small number of them fought the Nazis. Not even all the UA fascists.

There's no nuance or complexity here. All the Ukraians who fought against the ussr were genocidal fascists.
