"No investigation, no right to speak" is a helpful guideline. This is a good example of how to ask questions like these.
"Authoritarian" is not a meaningful descriptor because it applies to every state, hence "dictatorship of the proletariat/bourgeoisie". Russia has no colonies, is not imperialist, and is no more "authoritarian" than any country in the imperial core. Russia is a dictatorship of the bourgeoisie, but it's ended up resisting the imperial core and deserves critical support in that domain, not for its domestic policies.
