Fascism is an authoritarian system of government that feature a powerful central government that heavily restricts speech, has a command economy, secret police that persecutes dissidents, and vests large amounts of political power in one singular strongman leader.

Nothing the left every says about "fascism" bears any resemblance to this, and can be dismissed out of hand if they do not comport to this central definition.

"Fascism" was turned into a morality argument from the moment Germany surrendered in 1945. The true meaning and definition of this system of government is not taught in primary education deliberately so as to preserve the loaded morality baked into the modern use of the term.
