You seem to be using the term "fascist" to mean the same thing as "authoritarian"/"totalitarian"/"tyrannical"/"dictatorial"/"oppressive"/etc.
If you use the word in that way, then the Soviet Union was a fascist state.
But, to someone in the period between the World Wars, that would have seemed nonsensical – the Stalinists and fascists were at war with each other, on the streets of Italy and Germany, in the trenches of the Spanish Civil War. Both may well have been evil but only one was fascist.
Because there's another sense of "fascism", in which it refers to a specific type of authoritarianism/oppression/dictatorship/tyranny/etc devised by Mussolini and his associates, as opposed to just authoritarianism/oppression/dictatorship/tyranny in general. And in that sense, whether anything non-Italian counts as "fascism" is going to depend on which elements it has in common with the Italian archetype, and how significant you think each of those elements are.
I don't know where you got your first statement from (and without it the rest of your comment is meaningless). I gave you the list of criteria from Wikipedia and you pretended that it only had one item for some reason.
Stalinists/bolsheviks hated the Socialdemocrats just as much if not more than the nazis for quite a while. Does that mean that both groups couldn’t be socialist at the same time?
After Stalin decided to (literally) bankroll the the German invasion of France the French communist party openly and directly supported Hitler and Nazi Germany. Until they suddenly become the greatest enemies again purely due to “ideological” reasons after Barbarosa..
When it comes to totalitarianism the actual ideological differences become sort of meaningless. If Stalin tells you that the Fasicsts are the good guys now or that liberals/socialists/anarchists/etc. are just as bad, well.. it means that they are. Any diversion from the (very flexible) party line is just as bad as supporting the opposite side (or occasionally even much worse).
I’m not saying that there is no difference between Fascism, Naziism or [Stalinist/Bolsvhevik] Communism, far from it. However trying to define these as some sort of coherent ideologies based on fixed beliefs and principles is somewhat pointless due to their extremely shapeshifting nature.
