Because progress is an unadulterated good, it supersedes the rights of its opponents. This is evident in progressive indifference to the rights of those who oppose progressive policies in areas like sexual liberation.
This is one reason progressives have alienated moderate voters who turned to Donald Trump in 2016. The ideology of progress tends to regard the traditions that have customarily bound communities and which mattered to Trump voters alarmed by the rapid transformation of society, as a fatuous rejection of progress. Trump supporters’ denunciation of “political correctness” is just as often a reaction to progressive condescension as it is to identity politics.
Where liberalism seeks to ameliorate economic ills, progressivism’s goal is to eradicate them. Moynihan recognized this difference between Franklin Roosevelt’s New Deal, which he always supported — as exemplified by his opposition to Clinton-era welfare reform — and Lyndon Johnson’s Great Society, which he sympathetically criticized. The New Deal alleviated poverty by cutting checks, something government does competently even if liberals and conservatives argued over the size of the checks. The Great Society partook more of a progressive effort to remake society by eradicating poverty’s causes.
