I agree that Trump is wrong to call the media the “enemy of the people” and wish he would stick to less inflammatory words. His ­favorite charge of “fake news” makes his point well enough without any hint that he favors retribution on individual journalists.

But I am also concerned that media leaders refuse to see their destructive role in the war with the president. Few show any remorse over how the relentlessly hostile coverage of Trump is damaging the nation and changing journalism for the worse.

One obvious consequence is increased political polarization, with many media outlets making it their mission to denounce Trump from first page to last, day in and day out. Studies show 90 percent of TV news coverage is negative and the Times, Washington Post and CNN, among others, appear addicted to Trump ­hatred as if it is a narcotic.

This lack of balance permits little or no coverage of any of his achievements. How many people, for example, know about the employment records shattered by the jobs boom unleashed by Trump’s policies?
