I'm sorry, do I have to outline the numerous actions of Russia in and before 2013 that made it quite clear they were a fascist state? "He went to Nazi Germany before it invaded Czechoslovakia" is not the excuse you think it is.
"He went to Nazi Germany out of desperation, when he had numerous other choices that weren't Nazi Germany" is a moral statement. Or rather, a statement of lack of morals.
I hated him much less before the Ukraine War started. I was willing to accept that he had just made a dumb decision, and that he was just a coward for lending credibility to the fascist government he was under. After his comments and constant dodges on the Ukrainian War? I interpret his motivations in a much more negative light.
You feel emptier after having read someone criticize someone you've never met for choosing to flee to a fascist regime, support that fascist regime's talking points during an ongoing genocide, and still get hailed as a hero by some corners of the internet?
I think you're taking this altogether too personally.
