"Liberals" aren't liberal any more
Liberalism traditionally means liberty (tolerance for). In America, it has grown to mean the opposite. Classical liberals (libertarians) are liberal in both economics, and social arenas. Social liberals are liberal only in Social areas, but not in economic ones. Their economic authoritarianism, in the name of Social Justice, allowed them to became more and more "progressive" with regards to merging Socialist/Marxist economic policies (authoritarianism) to make up for past social injustices... then they gave up on social tolerance as well. They demand you agree/conform with them on social issues as well: the opposite of liberty or tolerance. Thus, they became so focused on Social Justice, they became anti-liberal authoritarians to get it.
Progressive liberalism (today's strongest DNC faction) took the ideas of Social Liberals to the next level. They believe that only central order, controlling businesses and individuals, in a high tax/regulation state, can lead to their new world order. That makes them highly aligned with what would have once been described in economic theory as Fascism. The federal control of the economy and business to further the social liberals agenda of wealth distribution for the greater good. The Greater good is defined by the political class, of course.
In Europe Anarchists are the far left, and Statists, Communists and Socialists (the ultimate power of the State) is "far right". In America, our far left are the statists. Our libertarians would be closer to Europe's "far left", but here they get called "Far right".
