Socialism is ALWAYS democratic, communism NEVER. Peoples' factory is communist, and every respected academic and political expert believes "Liberal Fascism" is "absolute drivel" (The Economist).
Pub dupes is perfect. Read the book.
Both communism and fascism are totalitarian; Fascism by definition, communism in practice. They remain direct opposites in their inherent policies; fascists demand state control, communists allege state control will end eventually. It never happens; still, NATIONAL socialism is much different that INTERNATIONAL socialism, few on the right have read enough to understand theory vs. practice, or the translation of the actual words. Socialism in much of Europe does not mean what it does in the US; conservatives are thrilled the NEW DEMOCRACY party won in Greece. Yet the word democracy is derided as applied to the US. That should give those posters a clue, but it has thus far escaped their notice.
Even look at practice, the means and intended goal of state control is fascism and communism is very different. Communism features state ownership toward the ends of promoting the interests of common laborers. Fascism leaves industries under private ownership and those owners keep collecting the profits on their enterprise, as long as they make the output the state desires.
