The short answer to the question in the headline is yes. Yes, they are. How Liberals got there from their 60’s roots is the subject of an article in the Wall StreetJournal by Shelby Steele titled The Exhaustion of American Liberalism. He is a bit kinder in his pronouncement, but we see connecting lines in his thesis to the foundation and expansions of the disconnected political class explored in other works like Angelo Codevilla’s Ruling Class v. Country Class and The Flight 93 Election by Publius Decius Mus.
We are speaking of people with little or no connection to any reality outside the political worldview they have constructed for themselves and the future it pretends. A class whose vitriolic intolerance for anyone who objects to being ruled in this way has taken on a cartoon-like madness.
