This "essay" should get an A as an undergraduate level product, and an F for its connection to reality.  The author confuses liberal democracy with liberalism and ignores the latter's move over the last couple of decades, at least, to impose its own form of authoritarianism on the population, in all of its manifestations.   Whining about Brexit and the election of Trump as indications of the end of democracy is pathetic.  Remember when rightwingers in the 70's were fearful that Pierre Trudeau was a crypto-communist and would end elections in Canada?  Take a good look in the mirror.
