I agree that different positioning should lead to different focus and rhetoric on the trends you try to combat as a leftist so guess OPs post can be true from a anglosphere perspective with the unhinged anti Russian craze and with the stanning of Nato across the board in the majority of the "left".. Here in the Balkans, at least in a bunch of countries there is some deep rooted anti-nato/western bias, especially among older generations (even if it doesnt come from a "left analysis") so naturaly the online and offline convo among regular people beyond the political sphere is more "balanced" and less unhinged and you dont have armies of baby leftists overnight shifting into pro Nato narratives or uncriticaly shallowing anything. Even the hardlne "tankies" here in greece are "both are worse and equaly shitty and should be opposed on equal capacities" regarding Russian imperialism and Nato in their stance .

On your last point i guess the Nazi problem in Ukraine more has to do with those far right groups being by far the most well organized , ideologicaly motivated , militarized and mobilized outside the liberal democratic electoral sphere and l having free reign to exert disproportinate to their numbers control and influence in the army, police and mayors or local politicians. And so at this point they do controll and lead the "defense" and armed forces in a lot of eastern and south Ukrainian cities and absorb more and more of their surrunding groups and also volunteers. There have been reports here in Greece from the Greek minority there (while also being anti putin) of how in Mariupol Azov basicaly is running the "defense" of the city in an utterly fascist and civilian-human shield fashion. FInding ideologicaly commited tattoo having Nazis among Ukrainian refugees is very unlikely i feel.
