Shouldn’t have said anything, now I’m getting paragraphs upon paragraphs about Putler and how the West has a moral obligation to prolong the war in Ukraine for as long as possible 
Also while apparently it can’t be denied that the far right has grown somewhat stronger in Ukraine, the Ukrainian military had to rely on militias such as Azov so they wouldn’t lose, we should not worry because they haven’t seen that much electoral success
it really depends what you mean by “not the actual government”, what kind of government enlists nazis into its military and makes entire large battalions of them and gives them large combat roles like the defence of key citys (azovstal etc) without being nazis themselves. When zelensky was asked what he thought of the praise of Bandera, a nazi collaborator that massacred jews in ww2 he said

I dont know about you, but me personally i would never call a jew hunting nazi an indisputable hero unless i myself was a nazi.
Moving on what are youre sources on denying the existance of langauge and culture, heres a statement from putin himself saying persecution on such basis is unjust https://tass.com/politics/1523075. (in response to people being unjustly jailed on such basis, my point being this not that attitude is non existant, it certainly exists, its that it doesnt exist at the very top level, the seat of power as it were)
Finally, if you think my sources are bullshit or that you cant trust the words of the leaders we can reduce it to its simplest form. If russia and ukraine were equally evil in their actions, russia would still be the lesser evil from my point of view due to me being a communist. Russia winning the war destablises the west, and destabilisation of the west increases the chances of communist movements (and non communist national liberation movements) being more successful in the global south. We can see such national liberation movements in the sahel states right now, who are throwing off the chains of their imperial masters more and more. A world where the US cannot win is a world where more such movements flourish.
And if you say well russia will become the imperial hegemon, and that will be just as bad as the us, that is an entire different discussion that I am not capable to disprove as it would require showing that russia does not act as an imperial power under lenins definition of imperialism, which would require economic analysis that im not capable of. Its my inclination that russia does not have the power or the ambition to become a unitary hegemon, I cannot imagine a world where the US is dethroned from hegemon and russia ascends to hegemon, while china, with 500 times the industrial capacity of russia, just sits there.
