My impression was that Russia had a real problem with reactionaries

To be precise

Russia is extremly Reactionary & yes Russia has real Problems with specific "White supremacy Nazis ,
you have to see it with view on Russias Demographic composition reactionaries and “Bloodline Ethnic Nationalist” are therefore an inherent danger to the State , it cracks down on them … they dont wanna catch the Leprosy that is Ethnic Nationalism , you can look at Ukraine for a Demosntation on how you loose all your Minority Territories if you deciede that those living there are Subhuman and not deserving of Rights … Ethnic fascism is an inherent Realpolitical danger to the Russian state in a Way in which it just isnt in the more “Nationstaty” European States… thats why Russia has a Real Problem with “White Supremacy” , no problems with hunting down LGBTQ+ and this “ethnicity neutral” nazi shit…

( and thats also why the West curts Navalny and other russian nazis … they know as well that white supremacy is a danger to to Russian statehood… why not amplify, you know they always post their “russia decolonized” maps …
