Please bookmark this post for several months from now, when I predict the Court eliminates the Voting Rights Act and somehow concludes that that later decision won't be too close to the election to prevent redrawing the maps.

The Supreme Court lets the Texas racial gerrymander go forward, overruling the three-judge district court. In so doing, it tells us that as of December 2025 it is too close to the 2026 election to redraw maps.

Holy shit.

Reuters reporting that new admin instructions on visas are if you worked at a platform in trust & safety or content moderation or on fact checking or online safety at an platform you *and your loved ones* are ineligible for H-1B visa.

www.reuters.com/world/us/tru...
The cable, sent to all U.S. missions on December 2, orders U.S. consular officers to review resumes or LinkedIn profiles of H-1B applicants - and family members who would be traveling with them - to see if they have worked in areas that include activities such as misinformation, disinformation, content moderation, fact-checking, compliance and online safety, among others.

This is what government censorship actually looks like: defunding entire fields, deporting researchers, and quite effectively chilling speech that helps people understand how our information systems are being exploited and calls out powerful people and platforms for their bullshit.
katestarbird.bsky.social Kate Starbird @katestarbird.bsky.social · 13h
For the last decade, the pervasive spread of bullshit & manipulation of online platforms have been widely recognized societal concerns. Now non US citizens studying those subjects can be labeled “censors” & denied visas or deported from the US. Censorship, indeed. www.reuters.com/world/us/tru...
Exclusive: Trump administration orders enhanced vetting for applicants of H-1B visa
An internal State Department memo said that anyone involved in "censorship" of free speech should be considered for rejection.

This is correct. But the Tokyo Tribunals were far harsher than the Nuremberg tribunals and are often criticized as "victor's justice." In any event, the only serious question IMO is whether this was a war crime or an extrajudicial execution chargeable under criminal codes.

GUARDIAN: “Per head, 🇺🇸 output is six times China’s, and yet, inexplicably, there seem to be more abjectly poor Americans than Chinese. 🇺🇸 inequality is breathtaking… keeps getting worse…”

Wanting to address this isn’t radical.

NOT wanting to is.

this is unironically good
Yes, but: While the number of X users in the U.S. has decreased since 2021, Reddit has seen an uptick, according to the Pew survey. 26% report using Reddit today, compared to 18% four years ago. Reddit is most popular among those ages 18-29, with roughly half saying they use the platform regularly.

I would agree that some of our ultra-wealthy immigrants have decimated our middle class—along with rest of the rich, greedy a**holes grasping for even more power and wealth. Look up, not down for our troubles.

Clearly Miller got some alone time with Donnie since the Mamdani visit.

Pretty hateful blanket condemnation from someone who married two immigrants.

When is Melania going to grow a spine and tell him to stop with this scapegoating?

This is what Trump thought was an appropriate Thanksgiving message. It's hard to know whether the lies, the hatred, or the disdain for our country and its laws are the worst part of this.

Trump: Most foreigners eating alive Great American Citizens and Patriots
The Thanksgiving post departed from Trump's, and the MAGA movement's, insistence they oppose "open borders" and instead favor "legal" immigration.

To begin with today, happy 117th anniversary to this entirely reasonable cat
Article from Des Moines Register 27 November 1908: NO BEER; CAT LEAVES TOWN Feline Deserts Connecticut Village That Went "Dry." WINSTED, Conn., Nov. 28. Fannie, a cat owned by Barreuther Bros., had liking for lager beer. When the town recently voted "dry" her owners went out of business and Fannie missed her drink. For some days she went to her saucer and cried for beer, but as none was forthcoming she disappeared. It is suspected she has gone to the nearest license town.
