LinkedIn probably wasn’t the best channel to post this, but I stand by it
A LinkedIn post from my profile, reading: “It's a very simple equation, really: Science communication needs to be accurate, it needs to be authentic, and it needs to be transparent. If you're not doing it that way, you're not doing science communication at all. In addition, *good* science communication is inclusive, it's ethical, it's sustainable. If you're not heeding these things, you're not doing science communication right. Which is why I am profoundly shocked by ostensibly reasonable people promoting the use of chatbots for science communication. Their use decreases factual accuracy. It decreases transparency. It decreases authenticity. Those things are true regardless of *which* chatbot you're using and regardless of *how* you're using it. Plus, the tech is not sustainable, not inclusive, not ethical. The promotion and use of Al chatbots is already damaging science communication and, if taken to the extreme, will be capable of quickly destroying it. Not through the rise of evil Al, but through ignorance on part of the users, rapidly destroying the trust that science communicators have been able to build over decades. Everything I will ever publish will be written by humans, and by humans only. If science communication goes the way of the robots, it will go there without me.”

i say this as someone with at least a mild background in cybersecurity — tiktok is now trump/fedgov spyware. you need to delete your account and app ASAP. just because the app isn‘t open doesn’t mean they won’t be harvesting your personal data to target you. queer folx get the fuck off that app

Can’t help but notice a lot of social media reports of Tik Tok censoring anti-ICE content in its first weekend under Trump-directed US management, and no mainstream news coverage thus far.

I mostly just stay off Twitter altogether but after double checking that the Walter Hudson post was still up I ran across this and just had to share so the Romancelandians who bought hand warmers could hear about the PROFESSIONAL GRADE LOGISTICS.
@GuntherEagleman on Twitter says, "BREAKING: The "No-Go-Zone" in Minneapolis is getting fully stocked like a pop-up leftist supply depot, free hand warmers, winter gear, coffee, food, milk, you name it. This is PROFESSIONAL-grade logistics. Someone is BANKROLLING this autonomous zone.

STATEMENT FROM MATT MOBERG, CHAPLAIN OF THE MINNESOTA TIMBERWOLVES IF YOU'RE A CHURCH POSTING PRAYERS FOR PEACE AND UNITY TODAY WHILE MY CITY BLEEDS IN THE STREET, MISS ME WITH THAT SOFTNESS YOU ONLY WEAR WHEN IT COSTS YOU NOTHING. DON'T DRESS AVOIDANCE UP AS HOLINESS. DON'T CALL SILENCE "PEACEMAKING." DON'T LIGHT A CANDLE AND THINK IT SUBSTITUTES FOR SHOWING UP. TONIGHT AN ICE AGENT TOOK A PHOTO OF ME NEXT TO MY CAR, LOOKED ME IN THE EYE AND TOLD ME, "WE'LL BE SEEING YOU SOON." NOT METAPHOR. NOT HYPERBOLE. A THREAT DRESSED UP IN A BADGE AND A PAYCHECK. PEACE ISN'T WHAT YOU ASK FOR WHEN THE BOOT IS ALREADY ON SOMEONE'S NECK. PEACE IS WHAT THE POWERFUL ASK FOR WHEN THEY DON'T WANT TO BE INTERRUPTED. UNITY ISN'T NEUTRAL. UNITY THAT REFUSES TO NAME VIOLENCE IS JUST LOYALTY TO THE ONES HOLDING THE WEAPONS. STOP USING SCRIPTURE LIKE CHLOROFORM. STOP CALLING YOUR FEAR "WISDOM." STOP PRETENDING JESUS WAS CRUCIFIED BECAUSE HE PREACHED GOOD VIBES AND PERSONAL GROWTH. YOU DON'T GET TO QUOTE SCRIPTURE LIKE A LULLABY, WHILE INJUSTICE STAYS WIDE AWAKE. YOU DON'T GET TO ASK GOD TO "HEAL THE LAND" IF YOU WON'T EVEN LOOK AT THE WOUND. THERE IS A KIND OF PEACE THAT ONLY EXISTS BECAUSE IT REFUSES TO TELL THE TRUTH. THAT PEACE IS A LIE. AND LIES DON'T GROW ANYTHING WORTH SAVING. THE SCRIPTURES YOU LOVE WEREN'T WRITTEN TO KEEP THINGS CALM. THEY WERE WRITTEN TO SET THINGS RIGHT. AND SOMETIMES THE MOST FAITHFUL THING YOU CAN DO IS STOP PRAYING AROUND THE PAIN AND START STANDING INSIDE IT. IF THAT MAKES YOU UNCOMFORTABLE— GOOD. GROWTH ALWAYS IS.

Patch alert! He must have made a New Year’s resolution to swim laps to lose weight. Made it across and back twice. Keep at it, bud.
A black bear (who is brown colored) swimming across a blue pool. He is headed for the floating blue pool ball we bought for him. He is also closer to my pool hoses than I am happy with, but you can (and we do) always buy new pool hoses. Can’t buy a new pool bear. Patch, pensively looking at the camera half submerged in the pool. Swimming past the blue ball.

Remember the other day when I was saluting my friend Greg Ketter, owner of Minneapolis’ DreamHaven Books? This is him the following day. Greg will never say this, so I will — now is a great time to buy books from DreamHaven. Support Americans who stand up vs. 🧊. dreamhavenbooks.com

A reminder to the news media: “conflicting accounts” is what you say BEFORE the incontrovertible video evidence appears. After that, your job is to ask why one side is lying, not to repeat the lie and pretend no one knows the truth.

Kare 11 local news just read, in full, this statement from Michael and Susan Pretti, the parents of Alex Pretti.

"Please get the truth out about our son."
Statement from Michael and Susan Pretti Parents of Alex Jeffrey Pretti “We are heartbroken but also very angry. Alex was a kindhearted soul who cared deeply for his family and friends and also the American veterans whom he cared for as an ICU nurse at the Minneapolis VA hospital. Alex wanted to make a difference in this world. Unfortunately, he will not be with us to see his impact. I do not throw around the ‘hero’ term lightly. However, his last thought and act was to protect a woman. The sickening lies told about our son by the administration are reprehensible and disgusting. Alex is clearly not holding a gun when attacked by Trump’s murdering and cowardly ICE thugs. He had his phone in his right hand and his empty left hand is raised above his head while trying to protect the woman ICE just pushed down, all while being pepper sprayed. Please get the truth out about our son. He was a good man. Thank you.

I am watching what is happening in Minneapolis on Ali Velshi and one of the ICE officers (off camera) literally says, “It’s like Call of Duty. Pretty cool huh?” as they shoot whatever it is they are shooting. Agents walking around, guns unholstered for no reason. This is insanity
