Agreed, but Rome in July would not have been possible.
Speaking of the future: @escaneu.bsky.social is still looking for a host for the meeting 2028!!!

Über 120.000 sagen: Rettet die Energiewende!
Stoppt Katherina Reiches "Netzpaket"!

Auch ein gemeinsamer Appell aus Wirtschaft und Zivilgesellschaft fordert einen Richtungswechsel der Bundesregierung für statt gegen die Erneuerbaren Energien in Bürgerhand.

Bitte verbreitet die Appelle!

Mal abgesehen von dem ethnonationalistischen Quark, Europa und die USA seien „christliche Zivilisation“ und historisch voller nobler „Entdecker“ ferner Länder: Möchte jemand Herrn Rubio darüber aufklären, wo wirklich „die ersten Universitäten der Welt“ entstanden?

The fact that large parts of the German media landscape “reported” on this White nationalist fever dream of a speech by Rubio as merely reaffirming the transatlantic alliance is so far removed from reality that it truly makes me speechless.

If it is fascism now it was fascism then but if you were wrong no need to pause to make a special effort to admit your error -- we don't have that much time now, please act right away, get organized, and then tell your followers what you are doing to stop fascism and what they too can do.

The president should be impeached and convicted, as should everyone responsible for these outrages. ICE should be disbanded. So should the Department of Homeland Security. And the people who have killed should be investigated and brought before judges and juries.

Wehrlose Menschen, die auf offener Straße von Regierungsbeauftragten ermordet werden; heimtückisch und aus niedrigen Beweggründen. Man sollte es offen aussprechen: Faschismus ist keine interne Angelegenheit eines Staates; schon gar nicht, wenn es sich dabei um den mächtigsten Staat der Welt handelt.

Stand With Minnesota A directory of places to give to as Minnesota defends itself from ICE occupation

So moved by the people of Minnesota who—drawing on LA, Portland, Chicago, DC etc—are writing a shining new chapter in the history of nonviolent resistance.

The rest of us need to be taking notes—and helping them!

"NYS Dept of Health & NYC Health Dept reject all recent and unilateral changes to the CDC immunization schedule."

This letter just went all to all medical providers in NYC. It sends an unambiguous message: Do not change your prior immunization practices.

FIVE YEARS & he has not been held accountable for one of the most disgraceful events in this nation's history.
Trying to overturn a fair election in an attempted coup against his own government is the very definition of TREASON. We can never move forward until this is fully adjudicated. #ShameOnUS🇺🇸

Because international media largely seems to struggle to choose the correct wording to describe what’s happening: the US, under the self describes „peace president“, attacked another country and kidnapped its president. That is factual, no matter how bad or illegitimate Maduro‘s rule is (very bad).

Wo bleibt eig. die Diskussion darüber, wie es manche öffentliche Institutionen und Politiker*innen noch rechtfertigen auf der Musk-Plattform zu bleiben? Muss man das so verstehen, dass es einfach keine Grenze gibt, die Musks Plattform nicht überschreiten kann?
Auch looking at you, @parlament.gv.at.

Crisisoverleg in top kabinet over BBB-mestplan: ‘Gevaarlijke patstelling’ Het politieke crisisoverleg over de mestplannen van landbouwminister Femke Wiersma duurt voort. Maandagavond gaan betrokken bewindspersonen én de vicepremiers van VVD en BBB opnieuw in beraad, maar…

Wiersma is volstrekt onhoudbaar als minister. Destructieve sabotagepolitiek, een ramp voor dieren, natuur, gezonde landbouw en zelfs haar eigen kabinet.

Dit is wat je krijgt als je het ministerie van Landbouw in handen geeft van lobbyisten van de agro-industrie.

Thoughtfully Shaping Our Digital Future
To the parties forming the government in the Senate and House of Representatives, as well as the outgoing administration,

We are writing to you in recognition of your crucial responsibility for shaping current and future AI policy, overseeing digitization, and upholding public values. We are a coalition of scientists, experts, and representatives of civil society organizations. We believe it is essential to address these matters together.

This letter has two objectives:

a) Provide context for current plans, including the AI Delta Plan, the AIC4NL position paper, and the Invest-NL AI Deep Dive. These investment proposals often rely on assumptions that lack scientific evidence and do not fully reflect public values.

b) To offer a constructive, well-substantiated alternative approach to digital futures based on people, nature, and democracy. We believe a collaborative process should guide decisions on the needs, scope, and nature of investments by bringing together scientists, civil society organizations, and stakeholders.

Die besten Methoden, um Rechtsextreme zu stärken, sind das Wiederholen ihrer Feindbilder & Forderungen bei Migration & die Umverteilung von Unten nach Oben & Kürzungen für den kleinen Mann.

Habe ich gerade die Politik unserer Regierung beschrieben?

Und wir wundern uns, warum die AfD stärker wird.
