Using the power of government to target political opponents is the textbook definition of fascism.
Tyranny.
Fascism is the economic relationship or the government with the means of production and labor, where the means of production are privately owned but government managed. We have a quasi-fascist government in the US. The private industries are tightly regulated so rent-seek and cooperate with the government.
Socialism and Communism is just slightly different, where the means of production are government owned, nationalization of all industry.
Most modern governments are a complex mix, not all one way or another, and there is always a private black market outside of government control.
