We’re watching a shift where AI simulates the cohesion and reinforcement that used to require an entire online community. A single person can now build a complete parallel reality with nothing more than a prompt window. Which seems bad.

There is no difference in practice between removing rights of individuals and leaving the ECHR. The end outcome is still the same, people lose rights. If human rights are an obstacle to your policy it is not the rights which are the issue, it is your policy. Labour going full Reform at this stage.

And we knew this. This wasn't speculation. We studied it, we had the talking points. We trained volunteers to explain this to people. It's not a surprise. Rich people don't flee places with good quality of life when we increase the quality of life. They might try to cheat us, but they don't leave.
NEW: The first two years of Massachusetts' millionaire tax has raised $3 billion more than expected.
And rather than driving the rich away, IPS researchers found that the number of millionaires has *increased.*

if you can fund moderately risky products that might 2x your money but you can also fund stupidly risky projects that might 100x your money and if it fails you get bailed out, then your options are clearly:
- modest bet: meek

- ridiculous bet: high reward, no real risk

In nothern Rio de Janeiro city, there is a couple of hills called Complexo da Penha. It's Comando Vermelho("Red Command", a drug gang), or CV, territory.
CV is the greatest gang in Rio, second in the whole Brazil.

🧵 Awful awful massacre in Brazil
Gente, é o maior massacre no Brasil desde o Araguaia. Entendo quem quer puxar pra Canudos ou Contestado ou etc, mas não podemos livrar a ditadura de 64 só porque ela escondia melhor seus corpos.
Morreram 41 guerrilheiros comunistas e mais de 1200 camponeses no Araguaia.

Frame: food stamps are used by undeserving / Black people
Negation: actually many people on food stamps are deserving / white
Kirby: THEY ARE STARVING PEOPLE ON PURPOSE. They are using racist tropes to justify it bc many people will find that persuasive. Everyone deserves to eat

Seeing all the content focused on centering all the people who need help who aren’t “fat, ghetto asses” and we can already see how the deserving/undeserving rhetorical lines are going to fall.

long shot but: I'm looking for a video game, that was already available on Steam 6-7 years ago, that was described to me as a sound experience with some psychedelic lights, kinda like a LSD trip, that should be enjoyed with headphones in a dark room.

Notably: every single rally (including in the small towns) was bigger than the surrounding police force available. That kind of image event is VERY IMPORTANT if you're, I dunno, demonstrating social coherence AGAINST a fascist government and it's makeshift gestapo.

In social movement studies, we talk about how marches and protests expand the threshold of acceptable risk so that people take more and bigger social risks IN PUBLIC, EN MASSE. This is extremely important for the bourgeois white folks holding signs and building social rapport.
Not a shitpost: #NoKings is feel-good performative activism for comfortable mostly upper and upper middle class white folks and that’s good, actually. Millions of people in the streets protesting a fascist regime is good. It is good for the normie baseline to be massive displays of public dissent.
