The message we keep having to repeat.

A reminder that the current SECDEF caught the eye of the president by championing the pardoning of American war criminals β€” men whose own units testified against them, and who were convicted by military juries

He should never have been nominated for, let alone confirmed in, this job

A reminder for those who are not aware: "remigration" is the process of deporting all non-white people from a country. It includes citizens and is, by definition, ethnic cleansing.

And to be clear: this is not fake. I just screenshot it myself.

I don’t know if anyone else notices or cares, but when I see a presentation in which the speaker uses obviously generated-AI images to illustrate their slides, it makes me immediately less confident in whatever other content they’re presenting.

It happened! The @nytimes.com profiled Paulina!

The Writer Who Dared Criticize Silicon Valley

Paulina Borsook’s β€œCyberselfish,” which offered dire predictions about the tech world’s love for libertarianism, is finding fans. It only took 25 years.

Many of us learned long ago that there is no "Legal Philosophy" in the Federalist Society. It is a club that gives members a leg up in the competition for certain judicial clerkships and jobs in the Trump administration. That is it. Period.

How does the NY Times not know this?

All I ever wanted to be was a scientist after I decided that being a fireman wouldn't work for me.

I've had to fight a lot of people for that career path, and I've won.

We need to build some real social stigma around being afraid of cities. You don't have to like them or live there, but a politics built this strongly around watching TV and going "ewww" is embarrassing, and people should be embarrassed by it. It's like "fear of werewolves" being your top issue.

1/ I’d like to share what’s happened since Sept. 30, the night of the most dramatic raid of the Trump administration’s Operation Midway Blitz in Chicago. Under the cover of darkness, 37 immigrants were taken from an apartment complex β€¦πŸ§΅

Never forget the same people defending pedophilia have spent years trying to convince the public that drag queens and trans people are a threat to children.

It’s all smoke and mirrors to allow the real predators to roam free.

This is inside baseball, but to me, there are three ways in which this development *bears out* Justice Jackson's unusual intervention Friday nightβ€”about which there was much confusion.

First, this makes it clear that a majority of the Court was *not* going to force the USDA to fund SNAP by Friday.

I'll get back to "party unity" as soon as the Senate Minority Leader tells us if he voted for the Democratic party nominee for mayor of his city.

I'm tired of party unity only ever running one way.

1/ The US Government has quietly removed a memorial to Black soldiers who died in World War II from the Netherlands American Cemetery in Margraten, South Limburg. The move follows a complaint from the right-wing Heritage Foundation to the American Battle Monuments Commission. ⬇️

Apparently all you needed to do to predict the NYC election results was read that one N.K. Jemisin novel.

The right-wing think tank which wrote the entire platform for the current president of the US is defending neo-Nazis, and meanwhile a substantial portion of American rabbis think the Muslim candidate for NYC mayor who has denounced antisemitism is the biggest threat to me as an American Jew.

Tucker Carlson’s lovefest with a white nationalist just blew up the Christian right A conversation with Nick Fuentes about Christian Zionism got many MAGA notables upset.

Christian Zionists often profess to love both Israel and the Jewish people, but for many of them, this devotion is intrinsically tied to their beliefs about the fate of the Jews in the end timesβ€”and it’s not pretty.

Hundreds of Alligator Alcatraz detainees drop off the grid after leaving site As of the end of August, the whereabouts of two-thirds of more than 1,800 men detained at Alligator Alcatraz during the month of July could not be determined by the Miami Herald.

More than 1800 detainees are missing after the closure of Alligator Alcatraz. Their families and lawyers can’t find them and they’ve vanished from the ICE database. Feels like this should be a much bigger story www.miamiherald.com/news/local/i...

In light of the PSF's recent loss of an NSF grant and attendant funding shortfall, I will be matching donations up to $5000. Send me your receipts.

Very happy if you've already donated for similar reasons but the point is to motivate *new* donations so be sure the timestamp is after this toot πŸ˜‰.

Once again, the main day of Tea Party protests had about 300,000 nationwide, but saw endless coverage.

The No Kings protests had about 7,000,000 nationwide, and many media outlets reacted with a yawn.

No Kings was nearly 25x as big as the Tea Party but the Tea Party got 25x the attention.

It is a scandal totally unprecedented in history that the Vice President has shared a video depicting the President as king. It’s an obscene violation of every founding American principle.

And nothing will come of it. It makes me physically sick.
