Speaking about theory of change: adapted from Prochaska theory (en.wikipedia.org/wiki/Transth...): how to quit bad habits I.e. our fossil addiction. Depending on where we are in the processus we are not ready to hear the same things and not ready to act the same way.

Free our self from bad habits… Ie. Adapted from from how to quit from smoking

Switzerland great since 1291: older democracy, one year turn presidency, constant share of 30% populist/climate deniers, but consensus as a rule. Read preamble of our constitution as a food for thoughts www.refworld.org/sites/defaul...

The 2926 swiss president with red hat with Switzerland great since 1291.

I have seen a post on the masculinist society that is presented as being the future. Let's imagine what will be this nice society... (description text in the alt ;-)), just a little bit of fun for this afternoon.

The Masculinist Society: A Dream World
A perfect world where "real men" battle in arenas to determine who has the biggest… chainsaw, bank account, or pickup truck. A dreamy aesthetic where nuclear power plants and diesel engines keep hearts warm in winter, while mundane administrative tasks—far too unmanly for human hands—are outsourced to computers crammed into sweltering data centers, nestled next to the reactors.
A dream world where "real men", behind the wheels of their convertibles, spend their days hurling insults at other drivers in traffic jams, when they’re not busy ordering heating oil to keep their wives warm—wives who, of course, are busy cleaning the house or picking up the kids from school at noon.
A dream world where "real men" dash to fast-food joints to grab their GMO-Pesticide-Burgers (GPBs) and the protein supplements they need to catch up to their gym buddy’s biceps.
A dream world where the "real man" prays the heat won’t be too unbearable on his construction site, as he lays down the black tarmac for the new Drive-In-Self-AI-Hospital—erected in a panic to compensate for the crippling shortage of healthcare workers.

There are different ways of defining Great Man, I let Americans choose the one they prefer. Added alt text.

Here is the transcription of the text from the image:

---

So as we look toward the next 250 years, we must also reflect on our shared responsibility to safeguard nature, our most precious and irreplaceable asset.

Millennia before our Nations existed, before any border drawn, the mountains of Scotland and Appalachia were one; a single, continuous range, forged in the ancient collision of continents.

The natural wonders of the United States of America are indeed a unique asset, and generations of Americans have risen to this calling: indigenous, political and civic leaders, people in rural communities and cities alike, have all helped to protect and nurture what President Theodore Roosevelt called the glorious heritage of this land’s extraordinary natural splendour, on which so much of its prosperity has always depended.

Yet even as we celebrate the beauty that surrounds us, our generation must decide how to address the collapse of critical natural systems, which threatens far more than the harmony and essential diversity of nature. We ignore at our peril the fact that these natural systems – in other words, nature’s own economy – provide the foundation for our prosperity and our national security.

On a News paper in Switzerland : what great men for a great country ! Translation by le chat in alt.

During a service at Bigotries and other low-level categories, the Trump administration did not mince words in sending its nemesis, the Islamic Republic of Iran, a message. This week, the televangelist and spiritual advisor to Donald Trump, Paula White-Cain, delivered this unsettling homily in the presence of the president at the White House:

"Jesus taught us so much through his death, his life, and his resurrection. He showed us that a great leadership and a great transformation require a great sacrifice. And, Mr. President, no one has paid the price that you have paid. That has cost you your life. You have been betrayed, arrested, and falsely accused. It is a familiar scenario that our Lord and Savior has already shown us. But for you, history has not stopped there, and for you, neither will it.

Paula White-Cain, who according to her says she is "not speaking to President Trump, but to God," continued her sermon by drawing a parallel between the American president and the Passover celebrations.

"God always has a plan: the third day, he rose, he defeated evil, he triumphed over death, the grave, and the tomb. And because he rose, we know that we can rise too. And Mr. President, thanks to his resurrection, you will rise. Because he was victorious, you will be victorious. And I believe the Lord is telling you this: thanks to his victory, you will be victorious in everything you undertake."

Apparently we have to go back to the basis: here they are for the Swiss civilisation (English language in alt text)

In the name of Almighty God!
The Swiss People and the Cantons,
mindful of their responsibility towards creation,
resolved to renew their alliance so as to strengthen liberty, democracy, independence and peace in a spirit of solidarity and openness towards the world,
determined to live together with mutual consideration and respect for their diversity,
conscious of their common achievements and their responsibility towards future generations,
and in the knowledge that only those who use their freedom remain free, and that the strength of a people is measured by the well-being of its weakest members;
adopt the following Constitution:

Solution by ChatGPT;-)

Here is a proposed equivalence glossary with alternative terms that can be used in research applications while maintaining the intended meaning:

Original Term Suggested Replacement
Climate change Atmospheric variability impact
Greenhouse gas emissions Industrial atmospheric outputs
Emissions Airborne pollutants
Racial equity Socioeconomic opportunity balance
Gender identity Individual demographic characteristics
Diversity, equity, and inclusion (DEI) Workforce participation and representation
Environmental justice Equitable resource distribution
Justice40 initiative Federal sustainability investment strategy

These replacements aim to retain the intent while avoiding potential restrictions in specific research applications. Let me know if you need further refinements.

This is a copy of my last Twitter Tweet. It was once valuable, but “X-version” has lost that purpose for me. In the spirit of ethics and respect, I share the Swiss Constitution preamble—a reminder of values that should guide us: unity, diversity, and responsibility for future generations.
