Today the racists/bigots take their place in the sun in politics. Yesterday they lived under rocks/sheets. How else has politics changed?.

Today the racists/bigots take their place in the sun in all walks of lives, not just politics. How else has politics changed. One of the biggest changes is that the powers that be are trying to run this country like a democracy when it's not a democracy. It is a Constitutional Republic. The chief characteristic and distinguishing feature of a Democracy is: Rule by Omnipotent Majority. In a Democracy, The Individual, and any group of Individuals composing any Minority, have no protection against the unlimited power of The Majority. It is a case of Majority-over-Man. This is true whether it be a Direct Democracy, or a Representative Democracy. In the direct type, applicable only to a small number of people as in the little city-states of ancient Greece, or in a New England town-meeting, all of the electorate assemble to debate and decide all government questions, and all decisions are reached by a majority vote (of at least half-plus-one). In both the Direct type and the Representative type of Democracy, The Majority’s power is absolute and unlimited; its decisions are unappealable under the legal system established to give effect to this form of government. This opens the door to unlimited Tyranny-by-Majority. 

  A Republic, on the other hand, has a very different purpose and an entirely different form, or system, of government. Its purpose is to control The Majority strictly, as well as all others among the people, primarily to protect The Individual’s God-given, unalienable rights and therefore for the protection of the rights of The Minority, of all minorities, and the liberties of people in general. The definition of a Republic is: a constitutionally limited government of the representative type, created by a written Constitution--adopted by the people and changeable (from its original meaning) by them only by its amendment--with its powers divided between three separate Branches: Executive, Legislative and Judicial. Here the term "the people" means, of course, the electorate.
