The question for me is ‘Where does this hatred come from’?
The answer is that it has a continuous legacy of nearly 2 centuries. I trace the Lefty position to the beginning of the industrial revolution and the French Revolution. I particularly identify it with the Jacobins.
The Jacobins put up the scaffolding and falling blades to use on the elites of France. Certainly a case of excess hatred, the beginning of the Lefty legacy. The Jacobins cohesive position was strong central government. Does that remind you of a president who believes in punishing ‘millionaires and billionaires and owners of the executive jets’?
In between the Jacobins and the current Lefty president are thousands of hate mongers. Look at Karl Marx, look at the American muckrakers and American communists and fellow travellers of every stripe. For the past 50 years, all one needed to say to provoke Lefty hatred was to suggest that Sen. McCarthy was right about Communists in government and the Rosenbergs and Sacco-Vanzetti were guilty.
The Left has a long legacy of hate and probably a long future in the same vein.
