Regarding the Aug. 16 front-page article “Trump again blames ‘both sides’ ”:

I was a preschooler in Germany at the end of World War II. My generation learned the horrific history of the Nazis and how they pulled a whole country along with them. The shame and guilt continue to lie heavily on my generation. Now, as a longtime citizen of the United States, I watched in horror the events in Charlottesville. But more chilling were the words of the president.

I can only imagine how descendants of slaves, Holocaust survivors and their descendants felt hearing the president equate those who had the courage to oppose with those who marched with the Nazi salute, the Nazi flag, torches, the Ku Klux Klan and the others Mr. Trump called “fine people” who marched along with them.

I felt the beginning of Nazi history repeating itself.

It is not enough for our representatives to denounce the alt-right. They must find the moral backbone to denounce those leaders, including the president, who have made excuses for the movement and its hateful ideology. They must refuse to be associated with the president’s party if it continues to value reelection chances and passage of its agenda over what is morally right and if it continues to tolerate this president, who has demonstrated that he lacks the moral authority to lead this great country. The danger is too great.

I admit what happened at Charlottesville and especially President Trump’s Tuesday rant put a genuine temporary scare in me, reminding me vaguely of my earliest childhood memory: Nazi hordes with banners and flags marching down Unter den Linden in Berlin, singing anti-Semitic, nationalistic songs (similar to those chanted by demonstrators in Charlottesville). The Weimar Republic leaders just stood by making excuses, so when I heard Mr. Trump blaming both sides, it really hit me. Only later, when I heard and saw the critical reactions to his diatribe, did I relax, confident that as a people and nation we are strong enough to resist and protect ourselves against this example of extremism.

Why should white-nationalist leaders take President Trump’s criticism seriously? He says that he wants to talk to his “base” directly, often through Twitter. So racist leaders will never believe him unless he makes a middle-of-the-night tweet that attacks them as #FailingWhiteNationalists and #CrookedRacists and #FakePatriots and ends it with his usual “Sad!”

But because he hasn’t, he probably never will.

To adapt Mr. Trump’s words: #FakeCriticism. Also: Sad! Except not so much sad as a horrifying stain on his presidency.
