If you really forgot, you need to be reminded. And the mention of one historical fact in this case may be more than enough.
31 January 1865 in the United States was adopted 13-I amendment to the constitution of the country, which prohibited slavery throughout the United States. It would seem, and here is the latest history of the United States? .. And despite the fact that in the current (2018) year - the year when the United States left the United Nations Human Rights Council - the United States turned exactly 5 (!) Years from that moment, as the instrument of ratification this 13 th amendment was sent to the US Federal Register from the last state, which gave good execution to the legislative act.

We are talking about the state of Mississippi, which almost 150 years did not consider it necessary to ratify the constitutional amendment on the abolition of slavery, and therefore formally (according to local legislation) slave system in Mississippi continued until 2013 year - already on the background of the fact that an African American was elected US President (Barack Obama).
It looks like some kind of phantasmagoria, but legally (and in the USA they are very sensitive to any legal nuance) - everything is like this: the slave system in the States was finally eliminated 5 years ago - in 2013 year - after ratification in the named state that kept "defense " until the last. And for some reason, human rights activists did not have any questions.
By the way, in the elections of 2012, in the state of Mississippi, Obama lost to Mittu Romney with a bang (563 thousand votes against almost 711 thousand). Lost Obama in Mississippi and in 2008 year. He scored 43% of the votes, and his then-main rival, John McCain - more than 56%.
So, if you say that American democracy is not more than five years old, then this is unlikely to be a serious mistake.
