We're not at war. Not a war crime. It's simply murder.

There was a discussion on LinkedIn yesterday about the good days of Academic Twitter before everything went to crap and we left. I'm curious why we haven't been able to recreate that here. A lot of the same folks are here, but there's not as much engagement. What's Bluesky missing? โš›๏ธ๐Ÿงช

I agree with the sentiment, but the math can't be right. If 400 people make up the richest stratum, then the rest of the people are not 50% of the remaining population...

So are you saying we SHOULDNโ€™T have raided that battery plant, put the South Koreans in leg irons and frog marched them off to a dank prison for about a week, @katiephang.bsky.social

But how else can we protect โ€˜Murica and stop all those criminal engineers from tearing us down by building factories

What happened to Charlie Kirk is also what happened to 20 children (ages 6 and 7) at the Sandy Hook Elementary School.

RFK Jr. is living in a pretend anti-vax world Unfortunately, he is wreaking havoc in the real one.

In a marathon hearing on Thursday before the Senate Finance Committee, RFK Jr. faced a barrage of questions from senators who were outraged by his recent actions.

In some cases, Kennedy appeared to promote flat-out lies.

Opinion | We Ran the C.D.C.: Kennedy Is Endangering Every Americanโ€™s Health

9 CDC Directors going back to 1977 speak out. What RFK Jr has done to our nationโ€™s public health system "should alarm every American."

It "is unlike anything we have ever seen at the agency, and unlike anything our country has ever experienced." www.nytimes.com/2025/09/01/o...

not just that he has no constitutional authority, there isn't even any particular legal or institutional mechanism by which the president can make anyone treat this as anything other than a weird advisory opinion.

"RFK Jr: We need to stop trusting the experts... Trusting the experts is not a feature of science or democracy...it's a feature of religion and totalitarianism."

Were he not a Kennedy...and wealthy...he'd likely be living his life out in a mental institution. Diagnosis: Dumb-Fuckery.

Honoring Ashli Babbitt Dishonors the Military If thereโ€™s no difference between upholding the Constitution and attacking it, then thereโ€™s no honor in service.

"She did not die defending the Constitution. She died trying to overturn it. She was not protecting lives at a gate in Iraq; she was forcing her way through windows in the Capitol to stop the peaceful transfer of power."
