from every reputable source I can find, Ukraine’s nazi/far-right/white supremacist problem isn’t any more problematic than any other country in the world.

In that case you’re not reading reputable sources.

The (Neo-)Nazis in Ukraine fuelled a civil war that killed, injured, and displaced thousands for the better part of a decade. (14,000 deaths, 30,000+ injured, and over a million displaced.)

For you to profess that you know what you’re talking about and conclude that Nazis in Ukraine are no worse than Nazis/the alt-right in any other country suggests at least four possibilities:

1. You don’t know what you’re talking about,
2. You know what you’re talking about and callously don’t care about the misery,
3. You know what you’re talking about and are downplaying the problem because you agree with the Nazis, or
4. You recognise that every NATO member state is also run by (neo-)Nazis (and Nazi-adjacents) and have decided that Ukraine is no worse than the US, France, Germany, Britain, Canada, Australia, etc, notwithstanding the civil war, because those other countries do the same thing as Ukrainian Nazis but outside their borders.

I’ll leave it for you to decide which one it is.

But pledging allegiance to a different superpower

No one here was doing that you. Ignorant. FUCK.

“There’s Nazis all over the place so what are we supposed to do?” And yet for some odd reason Nazis have a habit of not existing in communist countries. It’s almost as though nazism can be eliminated entirely by getting rid of the capitalist economic system that generates them!
