From what I can gather, Ukraine scrambled whoever who would fight after Russia annexed Crimea One regimen gained infamy for being led by neo-nazis, but the leaders were taken off and ran the political party instead that got 2% of the reported vote. No other stories seem to present themselves about current ethnic cleansing in eastern Ukraine. You can post them on the blockchain here; they may be downvoted but won't disappear.
Actually that is plenty documented. I posted the wiki link. That political party and the National Police Militia are proof of their power, and directly connected with the same Regiment that has declared war against Eastern Ukrainians who refused to go along with their Coup. That is the same Regiment that has been directly deployed to Donbass. The Neo Nazi element is present and obvious not only in the symbols and ideologies but in the recent laws they passed.
Their constitution explicitly prohibits such crap.
To conflict in Eastern Ukraine is entirely because the aggressors, the Neo Nazi who have refused to follow their own agreements. Twice. They instead decided to wage war against Eastern Ukrainians who wanted no part of their Coup. They have targeted Russian culture and Russian ethnic Ukrainians, but that, like I said, is just a Russian talking point. Because, on the blockchain, 14000 people who are targeted or engaging others because of their Language, isn't proof of genocide.
