Apparently, ICE is asking for people to stop calling its hotline to report an undocumented girl named 'Anne Frank' hiding in the attics of Republican lawmakers.

The key question in American politics now is whether public disapproval of Trump will grow fast enough to save our democracy before Trump builds such a crushing dictatorship that public opinion no longer matters.

“Take back control of our laws” so American fascists can decide them for us…
I don’t think so.
Just imagine if the EU demanded this of us.
Intolerable for it to even be on the table.
Intolerable to be at this table at all, frankly.
Another Brexit humiliation.

I find, as a writer and film maker, that "the grunt work, the boring shit" is often where the creative leaps and surprises occur, and I think most creative people will say the same.

No single human, at any point in history, has ever had so much of the world unite in ridicule.

No-strings-attached, zero-means-testing, no-questions-asked cash payouts have been proven, over and over again, to be the most effective form of charity/aid going.

It gets people in housing, and it saves the state money. We know this. It's fact, not theory.
An Oregon pilot program giving cash to homeless youths sees a staggering reduction in homelessness. The program gave participants $1,000 cash payments each month for two years, and at the end of the project's first phase, 91% of participants reported being in stable housing.

What we're seeing is exactly what we saw in the late 1940s, the late 1960s and the mid- to late 1970s: a concerted and hysterical campaign to delegitimise a Labour government, and indeed the very idea of Labour governments at all.

If the Venezuelan sailors were enemy combatants, then the 2nd strike is a war crime.

If the Venezuelan sailors weren’t enemy combatants, then both strikes are criminal murder.

It’s that simple.

Site in Kenya reveals 300,000 years of uninterrupted toolmaking. Archaeologists uncovered nearly 1,300 stone tools spanning 2.44 to 2.75 million years, showing that early hominins taught and replicated the same techniques across roughly 10,000 generations. buff.ly/zQvktxJ

On Bregman, I was there in the audience and I can’t see what the BBC have gained by removing this line except more bad publicity. I will say that no such edits or censorship occurred when I gave the Reith Lectures and free-speech defenders might want think about whether this is the world they want.

BBC removes description of Donald Trump as "the most openly corrupt president in American history" from the broadcast today of Rutger Bregman's Reith Lecture. I was among the several hundred people to hear the original at the lecture theatre
I wish I didn’t have to share this. But the BBC has decided to censor my first Reith Lecture.

They deleted the line in which I describe Donald Trump as “the most openly corrupt president in American history.” /1

Sometimes wonder if what the UK needs is a thinktank that doesn't do any new research, it just repeats obviously true statements that people try to ignore because they're inconvenient.

I suppose that ChatGPT is doing what we thought the search engine Ask Jeeves would do, though it lacks the required biting edge of contempt that you needed to ask the question at all.

A complete lack of awareness and a national embarrassment.
Just some British patriots in Benidorm, taking over a street in Spain to shout in their own language about unwanted foreigners. It’s a blessing that they are too thick to understand irony.

The fact of the matter is that there is no one path to improved health. When, however, we stigmatize, criminalize, & defund services for people w/substance use disorders, it creates a clear path for worsening health. We must stop the erosion of harm reduction. @nejm.org
