Playing semantics doesn't negate the fact of all of the various isms result in total dictatorial rule through one political party and/or total economic control.  The ultimate goal of Capitalism is owning and controlling all aspects of economic systems.  The melding of both is fascism.  Republicanism is nothing more than a falsely named party no longer resembling anything of its original ideals devoted to a Constitutional Republic of individual human and civil rights under a Constitutional system of laws.  The current "Republican" party is made up of fascist individuals denying human and civil rights, advocating a national christian religion violating those same rights, and free market capitalism whose ultimate goal is Corporate Oligarchy control of the economy through market manipulation aided and abetted by a political dictator in absolute control of government.  Working in collusion, they create the Fascist state which is just one more form of Totalitarianism.  No individual freedom.
