So the problem isn’t that they are Nazis, it’s that it is “fueling Russian propaganda”.
By the end of the 1930s the Ukrainians had suffered a Holocaust level genocide -- 5 to 11 million murdered (depending on whose estimate you believe) by an NKVD orchestrated artificial famine.
To many Ukrainians, the Nazis were liberating them from Communist mass murderers.
Much like Jews later saw the Communists as liberating them from Nazi mass murderers.
Other than wearing that patch, what does their alleged Nazism consist? A statue of Banderas? They also have a monument honoring the dead of Babi Yar. It’s unfortunate that Banderas made that symbol popular in Ukraine long after the Nazis wore out their welcome. But on parades in Latvia, the old geezers also wear that symbol on their SS uniforms. Hell’s Angels seem to like it, too.
At present, the Ukrainians are rightfully defending their homes against invasion by their former imperial masters. Nothing Nazi about that, patch notwithstanding.
The Azov Battalion, despite their use of that symbol and their many atrocities, were not Nazis. They were Cossacks. Nazis are systematic, relentlessly-monstrous man machines. Cossacks are monstrous, too, but their crimes are crimes of passion. They’re wild men. They wake up in the morning hung over and full of regrets.
