I don't think any kind of nationalism, ethno- or otherwise, is healthy. I also think anyone with a healthy sense of justice must hate the State. It claims a monopoly in justice, but monopolies always produce waste and abuse.
No peaceable person should be compelled to submit to a government they believe is opposed to their interests. Ukraine as we know it today is younger than I am. Politics turns every dispute into a zero-sum game, and if there can be no compromise, it is time to split apart instead of continuing to fight. Maybe the Donbas region should be free to declare independence or change allegiance? As an anarchist, I favor secession to the individual level.
That said, nothing Russia has done militarily in the last month can be supported. Little news reporting I see seems trustworthy as I try to navigate the maze of propaganda assailing me from all sides, but military invasion is a supreme act of injustice. What Russia is doing to Ukraine is no better than what the US did to Iraq, Afghanistan, Syria, Somalia, etc.
Anyway, that is my 2¢.
Must have been something good if YouTube censored it.
