Slop.

Russian nazis aren't in positions of power, whereas in Ukraine they run the intelligence branch, they're mayors, they're police chiefs, they're in the cabinet. Azov wasn't like a "kind of" nazi militia, they were explicitly nazis and the Ukrainian government has taken them into the military and use them as elite troops. Russia's militarized nazis were in the Wagner group, which you might remember were used in brutal and unforgiving ways which conveniently liquidated of a bunch of them. It's impossible to identify why the Russian government chose to use them as expendables, but it sure seems like a decision based on not valuing the lives of nazis whatsoever. Furthermore, Russia never had a fascist government engaging in pogroms and ethnic cleansing, whereas Ukraine has the Banderite fascists in their history and they officially venerate them. They are systematically renaming things with Soviet names to name them after Banderite scum. In 2014, the US backed fascist factions who overthrew the government and murdered opposition party supporters en masse.

Then there's my "favorite" CIA-related detail about this, Project Aerodynamic (link intentionally broken because it's linking directly to the CIA website) cia dot gov/readingroom/docs/AERODYNAMIC%20%20%20VOL.%201_0118.pdf

CIA started relocating nazis and banderites to Ukraine in the 1950s with the explicit intention of empowering a fascist opposition with the ultimate goal of destabilizing the USSR and creating a fascist breakaway state. They never stopped this type of thing, that's why Azov were acting as the CIA's pawns on the ground as early as 2014.
