Facism - a ruling system giving government nearly total control of all people and all things. People retain private property ownership, but the government tells them what to do with it. Examples were government in Germany under Hitler's 4th Reich and in Italy under Mussolini during World War 2. Nazism under Hitler. Examples were government under the old Soviet Union under Stalin in World War 2 and probably the current Bejing, China government.
Socialism seeks governmental ownership of all property.
Fascism allows private ownership of property, but tells the owner what to do with it. Historically, both Fascism and Socialism degrade in totalitarianism, as does Nazism, Communism and Democracy. Fascism is supported by most Democrats, although they call it Socialism. Generally, those Democrats are a bunch of ding-dongs that no one in real life pays any attention to. But, they all make big noise.
