Fascism is a response to Communism. Fascism was made after WWI, after the Soviet Revolution. Fascism was invented to stop Communism. The premise of Fascism is the inversion of Communism. In response to whatever Communists want to do, Fascists say they want to do the opposite.

Fascists did look at Communist concepts and changed them to be the opposite. For example, Mussolini believed that one of the main pillars of fascism is class collaboration, which is the opposite of class struggle. Marxists believe that the working class should struggle against the capitalist class, with the goal of abolishing class. Fascists believe that the working class should collaborate with the capitalist class for the purposes of Nationalism, they think that their own nation will become stronger if the working class just submits to the capitalist demands.

As someone else pointed out, "race communism" does sound a lot like "national socialism". I think this demonstrates how Fascists distort communist concepts. Fascists want to trick workers away from being Communist. Even like the symbolism of Fascism itself feels like a distortion of communism. Fasces, a bundle of sticks being stronger than a single stick. This seems like a distortion of the concept of labor organizing.

There is a concept in fascism, nazism, white supremacy called "race consciousness", someone who is conscious of their own race in relation to other races. I believe Mussolini had this concept as well.

Communists believe in class consciousness. Fascists believe in race consciousness. Communists believe in class war. Fascists believe in race war. Class war is real, race war is not real.
