Holy shit what an incredibly stupid thing to say.
In what universe were Stalin, Mao, and Pol Pot left-wingers?
Politics is action. If your actions (domination and oppression in pursuit of the benefit of the few, as opposed to peace and cooperation and liberty in pursuit of the benefit of all) are those of right-wingers, you’re a right-winger. The rhetorical language you employ is irrelevant.
Unless you seriously believe that North Korea is democratic–in which case you’re just a moron.
