"Between 1976 and 1979, 86 percent of high school seniors had gone on a date; between 2010 and 2015, only 63 percent had ... During the same period, the portion that had ever earned money from working plunged from 76 percent to 55 percent. And the portion that had tried alcohol plummeted from 93 percent between 1976 and 1979 to 67 percent between 2010 and 2016." According to a new study, teens increasingly put off traditional markers of adulthood. Is it the internet? Well, these trends started before the internet really took off. Is it more homework or a busy after-school schedule? No, teens today spend less time on homework. Is it some cultural trend attributable to race, gender, or socioeconomic status? Actually, it seems to cut across all groups. Maybe teens just decided adult life wasn't all it's cracked up to be.

"When students were asked whether the First Amendment protects 'hate speech,' 4 in 10 said no. This is, of course, incorrect. Speech promoting hatred -- or at least, speech perceived as promoting hatred -- may be abhorrent, but it is nonetheless constitutionally protected." Here's a little more confirmation that college students don't necessarily get the gist of free speech. This is one issue where people tend to talk out of both sides of their mouth. (Or even "many sides" ...)

Breaking News: Honky Cat challenges Rocket Man. World extinguishes like a candle in the wind. SAD! Songs Say So Much. During his first major UN address, President Trump delivered tough talk to Iran and North Korea, again referring to Kim Jung Un as "Rocket Man" and declaring that: "The United States has great strength and patience, but if it is forced to defend itself or its allies, we will have no choice but to totally destroy North Korea." Here's my issue with the bombastic North Korea talk: First, it's worth noting that, so far, the citizens of North Korea are Kim Jung Un's primary victims. Totally destroying them has been his family's specialty. It shouldn't be ours. Second, a core strategy of the Kim dynasty has been to manufacture a threat from the US and use the fears of that threat to maintain power and justify the starving of their own people. Talk of fire, fury, and total destruction plays right into that narrative. You may see it differently, but to paraphrase another Elton John line: Don't Shoot Me, I'm Only the Internet Editor.

"The point is that Facebook has a strong, paternalistic view on what's best for you, and it's trying to transport you there. 'To get people to this point where there's more openness – that's a big challenge. But I think we'll do it,' Zuckerberg has said. He has reason to believe that he will achieve that goal. With its size, Facebook has amassed outsized powers. 'In a lot of ways Facebook is more like a government than a traditional company,' Zuckerberg has said. 'We have this large community of people, and more than other technology companies we're really setting policies.'" Franklin Foer on Facebook's war on free will.

"Of a total of 1.1 million Rohingya that remained in Burma despite repeated waves of violence since the late 1970s, more than 420,000 have fled to neighboring Bangladesh in just the past month. New arrivals are building makeshift settlements near established camps where hundreds of thousands of Rohingya refugees from previous exoduses already live. Most are women, children and the elderly. Conditions are dire. Food is scarce. Aid agencies are worn thin. The monsoon rain is torrential." WaPo provides a look at the ‘ethnic cleansing' of the Rohingya, and we got here.
