The scientists are all talking like it’s a sure thing.

On August 21, the “moon” will pass between the Earth and the sun, obscuring the light of the latter. The government agency NASA says this will result in “one of nature’s most awe-inspiring sights.” The astronomers there claim to have calculated down to the minute exactly when and where this will happen, and for how long. They have reportedly known about this eclipse for years, just by virtue of some sort of complex math.

This seems extremely unlikely. I can’t even find these eclipse calculations on their website to check them for myself.

Meanwhile the scientists tell us we can’t look at it without special glasses because “looking directly at the sun is unsafe.”

The strangest part about the continued personality cult of Robert E. Lee is how few of the qualities his admirers profess to see in him he actually possessed.

Memorial Day has the tendency to conjure up old arguments about the Civil War. That’s understandable; it was created to mourn the dead of a war in which the Union was nearly destroyed, when half the country rose up in rebellion in defense of slavery. This year, the removal of Lee’s statue in New Orleans has inspired a new round of commentary about Lee, not to mention protests on his behalf by white supremacists.

The myth of Lee goes something like this: He was a brilliant strategist and devoted Christian man who abhorred slavery and labored tirelessly after the war to bring the country back together.

Since the president of the United States cast his lot in with white supremacists in his #NotAllNazis moment this week, the nation’s military service chiefs have responded with full-throated statements rejecting extremism and intolerance.

These statements have alarmed many. “If we lived in a different sort of country,” Fred Kaplan wrote in Slate, “this could fairly be seen as the prelude to a military coup.”

And I have some sympathy for this alarm.

As I have written in these pages, I am growing increasingly worried about the politicization of our military. And when I see the military appear to resist the impulses or tweeted policy preferences of the president, I am very conscious that—to build on an astute observation made by my friend Erin Simpson early on in this administration—some of the actions that protect the fabric of American society in the near term could be detrimental to American institutions in the long term. A politicized military that endures beyond this administration, for example, is not in the interests of the American people.

In his Tuesday press conference, Donald Trump talked at length about what he called “the alt left.” White supremacists, he claimed, weren’t the only people in Charlottesville last weekend that deserved condemnation. “You had a group on the other side that was also very violent,” he declared. “Nobody wants to say that.”

I can say with great confidence that Trump’s final sentence is untrue. I can do so because the September issue of The Atlantic contains an essay of mine entitled “The Rise of the Violent Left,” which discusses the very phenomenon that Trump claims “nobody wants” to discuss. Trump is right that, in Charlottesville and beyond, the violence of some leftist activists constitutes a real problem. Where he’s wrong is in suggesting that it’s a problem in any way comparable to white supremacism.

One day last summer, around noon, I called Athena, a 13-year-old who lives in Houston, Texas. She answered her phone—she’s had an iPhone since she was 11—sounding as if she’d just woken up. We chatted about her favorite songs and TV shows, and I asked her what she likes to do with her friends. “We go to the mall,” she said. “Do your parents drop you off?,” I asked, recalling my own middle-school days, in the 1980s, when I’d enjoy a few parent-free hours shopping with my friends. “No—I go with my family,” she replied. “We’ll go with my mom and brothers and walk a little behind them. I just have to tell my mom where we’re going. I have to check in every hour or every 30 minutes.”

Those mall trips are infrequent—about once a month. More often, Athena and her friends spend time together on their phones, unchaperoned. Unlike the teens of my generation, who might have spent an evening tying up the family landline with gossip, they talk on Snapchat, the smartphone app that allows users to send pictures and videos that quickly disappear. They make sure to keep up their Snapstreaks, which show how many days in a row they have Snapchatted with each other. Sometimes they save screenshots of particularly ridiculous pictures of friends. “It’s good blackmail,” Athena said. (Because she’s a minor, I’m not using her real name.) She told me she’d spent most of the summer hanging out alone in her room with her phone. That’s just the way her generation is, she said. “We didn’t have a choice to know any life without iPads or iPhones. I think we like our phones more than we like actual people.”

While Donald Trump is on vacation, there are major renovations going on in the West Wing. Perhaps they’ll alter plans and include a portcullis and a moat, because the White House is under siege.

The president is once again facing loud denunciation (though so far little else) from members of his own party. Vice President Pence is cutting short an overseas trip and returning home to an administration in crisis. And Wednesday afternoon, the president announced he was pulling the plug on a manufacturing council and a strategy and policy forum, both comprised of business leaders, after a spree of defections in reaction to Trump’s handling of violence in Charlottesville.

The white-nationalist forum Stormfront hosts discussions on a wide range of topics, from politics to guns to The Lord of the Rings. And of particular and enduring interest: genetic ancestry tests. For white nationalists, DNA tests are a way to prove their racial purity. Of course, their results don’t always come back that way. And how white nationalists try to explain away non-European ancestry is rather illuminating of their beliefs.

Two years ago—before Donald Trump was elected president, before white nationalism had become central to the political conversation—Aaron Panofsky and Joan Donovan, sociologists then at the University of California, Los Angeles, set out to study Stormfront forum posts about genetic ancestry tests. They presented their study at the American Sociological Association meeting this Monday. After the events in Charlottesville this week, their research struck a particular chord with the audience.

Since 1907, Portland, Oregon, has hosted an annual Rose Festival. Since 2007, the festival had included a parade down 82nd Avenue. Since 2013, the Republican Party of Multnomah County, which includes Portland, had taken part. This April, all of that changed.

In the days leading up to the planned parade, a group called the Direct Action Alliance declared, “Fascists plan to march through the streets,” and warned, “Nazis will not march through Portland unopposed.” The alliance said it didn’t object to the Multnomah GOP itself, but to “fascists” who planned to infiltrate its ranks. Yet it also denounced marchers with “Trump flags” and “red maga hats” who could “normalize support for an orange man who bragged about sexually harassing women and who is waging a war of hate, racism and prejudice.” A second group, Oregon Students Empowered, created a Facebook page called “Shut down fascism! No nazis in Portland!”

It could have been so much worse.

Like ISIS attackers in Europe, the Charlottesville murderer used a car as his assault weapon. But Charlottesville this past weekend was crammed with anti-social personalities carrying sub-military firearms. It could just as easily have been one—or more—of those gun-carriers who made the decision to kill. If so, Americans might this week be mourning not one life lost to an attack, but dozens.

As recently as 2009, the nation retained a capacity to be shocked when individuals carried weapons to political events. Such was the case in Phoenix, Arizona, on August 18, 2009:

A man toting an assault rifle was among a dozen protesters carrying weapons while demonstrating outside President Obama's speech to veterans on Monday, but no laws were broken. It was the second instance in recent days in which weapons have been seen near presidential events.

When Donald Trump failed to single out and denounce Nazis, Ku Klux Klan members, and their allies Sunday, even after they marched by torchlight through an American city, where one among them ran down an anti-racist protester, I noted the historic failure of presidential leadership—a failure underscored by the praise that white supremacist leaders heaped on his approach—and called on Congress to step into the breach, reasserting the nation’s conscience by censuring the president.

In the days that followed, Trump buckled to widespread pressure to single out the white-supremacist groups, naming them in a statement that he read from a teleprompter. But he subsequently declared, in a combative, unscripted press conference Tuesday, that there were some good people on both sides of the Charlottesville protest, implying that good people marched alongside swastikas and KKK members.
