Seems like the talk about Nazis in Ukraine is based on the view that Russia (using the USSR) model is nicely socialist. Which opens a question about whether today's Russia is even remotely socialist.

I'm not a political scientist, but I thought the general definition of socialism was the public ownership of the means of production under an authoritarian government, while fascism is the private ownership of the means of production under an authoritarian government.

By those definitions, there are hardly any communist countries around any more (maybe Cuba?) and plenty of fascist ones--including Russia as perhaps the outstanding current example.

That line of argument says that Russia accusing Ukraine of being run by Nazis is simply projection.
