-If you vote for money for ICE.
You are complicit. This is the gestapo. You're on the wrong side. You can't pretend not to know.

Happy to recommend this book. I read it about 5 years ago and it speaks to how we got to today.
In case you didn’t realize it…
This book is about white Christian nationalism.

As someone who straddles the worlds of math and physics, I sometimes get frustrated when mathematicians use various math functions randomly to describe a moving object (looking at you calculus) that are ridiculously unlikely to be the result of a physical setting: e.g.cubics multiplied by exponent..

I teach a class for science majors looking at ethical and faith connections to science on a variety of subjects that vary yearly. Last week I asked them to think about communicating science publicly in the current anti-science atmosphere in the US. The journal responses show more passion then ever.

So often in the last few years when we sing triumphal worship songs at church, I cringe at the war imagery often embedded and used by Christian nationalists and other right wing Christians to picture themselves as fighting for God. The Holy Spirit gave me a new image this morning.

I think the disconnect we’re seeing online is between pundits who are imagining a Charlie Kirk in their heads and professors who have lived for a decade with the (often literal) targets he and his anti-free speech organization placed on their backs.
Weird how when a Trump supporter, white supremacist, and reportedly, a former member of Turning Point USA shot up Florida State University (FSU) several months ago and killed two people - there wasn't the same national conversation about "political violence." www.mediaite.com/news/mass-sh...

Every single religious organization and denomination needs to raise holy hell about this - and never let these men have a moment's rest until this funding is restored.
And if you tell me you are a Christian and think this is OK, I'll tell you that you have no idea what it means to follow Jesus.

A new study models impact of the implosion of US-funded disease treatment & prevention globally. It suggests Musk and Rubio will go down among history’s greatest monsters if funding is not restored.
In short: 10s of millions will die, millions of children.

Reading Culture Making by Andy Crouch and his argument that the most important cultural changes always happen slowly. It is comforting to think that the chaos of Trump 2.0 is not lasting change despite its quickness. But discomforting to think about the decades of slow changes that underlie it.

A useful article about how face-to-face encounters and personal connections can combat misinformation. As also espoused by @katharinehayhoe.com!
Countering #misinformation isn’t just about the facts—it’s about how those facts spread through social networks and communities. #Science being right isn’t enough; it must be accepted within social circles to make an impact.
