Equal rights is an undefined, ambiguous term that means different things to different people, depending on the context. The term was used by promoters of a gender-neutral society when they invented the name "Equal Rights Amendment", a name that was never part of the proposed amendment.
In the past the leading figure of totalitarian Nazism, Hitler, who exhibited the traits of disturbed character and let himself to be called "Der Führer", used language of 'equal rights'. He argued that if the western powers would not disarm, the principle of basic equity as well as the pride and prestige of a great nation demanded that Germany should be permitted to rebuild its armed forces, reduced to punny levels at the 1919 Treaty of Versailles, to similar levels. Many, not just in Nazi ranks, considered his claim on rearmament as the best way to secure German defence and demand to be on par with the western powers in terms of military strength a compelling argument. Where Hitler pulled a masterstroke was in persuading them for years that he was striving for peace, not war.
