You keep clinging on little details. Russia is an empire due to how many smaller nations were conquered to the east. Just like USA is an Empire etc. Current rebranding doesn't change the fact.
Fuck ton of countries were fascist just before and during WWII. It's not a serious argument to make here. Fascism is just getting to power without democratic means.
And for the Finns. I honestly feel sad for you, if you believe there is a conspiracy theory that managed to brainwash an entire nation.
Just beause Russian Empire rebranded itself it ia still basically the same size with the same subjugated people. The same yakut people are still subjugated. The cataclysmic event you're talking about is workers revolt. The other is the collapse where quite a bit of countries at least managed to escape. All we can hope is for the fall of russia and for other cultures to emerge.
Here is the common definition: Fascism - A system of government marked by centralization of authority under a dictator, a capitalist economy subject to stringent governmental controls, violent suppression of the opposition, and typically a policy of belligerent nationalism and racism.
Even if you have 2 fascist countries, their goals and decisions are and usually is different.
And for consent. Look at bloody linux distros. Even if people actually want consent, it is basically impossible to achieve. Every expert will interpret it differently and you will have multiple narratives.
