In Mr. Sowell's book he mentions the term 'Liberal' zero times, as I recall. He uses specific cases and in some cases individual names tied to those historical events. (e.g.The War on Poverty, President Johnson). My 'labeling' of liberal came from an endorsement of the book written by Scott McConnell, Wall Street Journal. He wrote, "This is as compelling an explanation as any for the seemingly, disproportionate amount of condescension and politically correct invective that emanates from the liberal side of the political spectrum toward the conservative opposition."
