Actually, I would argue they were very similar. And their mutual antagonism was entirely due to their similarity.
Remember, prior to the invasion of Poland, there was a real possibility that the British and French may have allied with Germany to run the Soviets out of Finland. Further, despite the writings in Mein Kamph, Stalin and Hitler brokered a treaty to divide Poland. Both dictators sized up the situation and determined they could play the peace angle for a period of time before readying their respective militaries to go after each other. Hitler flinched first and the alliance to defeat him was born.
From a practical consideration, Stalin and Hitler employed precisely the same agenda -- a craven quest for totality of personal power and development of a cult of personality.
Additionally, both employed brutal methods against segments of their local populace. Stalin embarked upon a purely genocidal campaign of forced industrialization which resulted in the sale of grain for capital to the point where millions were starved to death from induced famines.
Hitler's efforts against Jews is of course well documented.
Both employed ruthless purges. Both employed state police units to develop a power base built upon fear.
Both used state control of private business. Even in Italy the Fascist government did the same by nationalizing basic industries.
As I said, fascism is total submission of individual liberty to the government. Your first quote supported that.
However, fascism is not by any means restricted to right or left politics. Hugo Chavez is morphing to a dictator and his ultimate quest appears to be fascism under a left ideology.
Augusto Pinochet was a dictator seeking fascism under a right ideology.
As I wrote, fascism is a quest for state power over the citizenry with alienation of individual rights over the state.
