This article by Dennis Prager lays out his belief that liberal – make that leftist – thinkers have pretty much abandoned thought.
The highest-ranking Democrat in America, Senate Minority Leader Harry Reid, described the Senate bill making English the national language of the American people as "racist." And the New York Times editorial page labeled the bill "xenophobic." Welcome to the thoughtless world of contemporary liberalism. Beginning in the 1960s, liberalism, once the home of many deep thinkers, began to substitute feeling for thought and descended into superficiality. One-word put-downs of opponents' ideas and motives were substituted for thoughtful rebuttal. Though liberals regard themselves as intellectual – their views, after all, are those of nearly all university professors – liberal thought has almost died. Instead of feeling the need to thoughtfully consider an idea, most liberal minds today work on automatic. One-word reactions to most issues are the liberal norm.
