Nope, fascism is like 90% socialism.

Soon after he arrived in Switzerland in 1902, 18 years old and looking for work, Benito Mussolini was starving and penniless. All he had in his pockets was a cheap nickel medallion of Karl Marx.

Following a spell of vagrancy, Mussolini found a job as a bricklayer and union organizer in the city of Lausanne. Quickly achieving fame as an agitator among the Italian migratory laborers, he was referred to by a local Italian-language newspaper as "the great duce [leader] of the Italian socialists." He read voraciously, learned several foreign languages, (2) and sat in on Pareto's lectures at the university.

Mussolini's election to the Executive was part of the capture of control of the Socialist Party by the hard-line Marxist left, with the expulsion from the Party of those deputies (members of parliament) considered too conciliatory to the bourgeoisie. The shift in Socialist Party control was greeted with delight by Lenin and other revolutionaries throughout the world.

From 1912 to 1914, Mussolini was the Che Guevara of his day, a living saint of leftism. Handsome, courageous, charismatic, an erudite Marxist, a riveting speaker and writer, a dedicated class warrior to the core, he was the peerless duce of the Italian Left. He looked like the head of any future Italian socialist government, elected or revolutionary.
