I suspect this guy is another post-East Bloc boomer who's nostalgic for the USSR more out of nationalist pride than genuine socialism, but the fact he said Leningrad instead of Stalingrad gives me mild hope. Weirdo Russian NatBols trend to be pure Stalin Stans while repeating that "Lenin was a German spy" BS.
Let's be fair here, dudes with Stalin and Nicholas II tattoos side-by-side are fair to seriously suspect of having an ideology that would boil down to NazBolism, since they are worshiping a guy falsely accused of doing anti-semitic pogroms and also a guy who actually did them.
