Wait, Marc, I've got a screenshot that includes Tara @aetiology.bsky.social (although we're down to half of @germhuntermd.bsky.social, sorry!). Was a great discussion but I hope we didn't pile on @drneilstone.bsky.social too much... Luckily he was tough and gracious at the same time.

I"Het is waar dat geen enkel gesprek perfect is en dat er altijd een risico is dat een discussie uit de hand loopt. Daarom is het nodig dat de universiteit zorgt voor ondersteuning om veilige klaslokalen te creëren waarin gepassioneerde docenten en open-minded studenten met elkaar in gesprek gaan."

Opinion | What’s Happening Is Not Normal. America Needs an Uprising That Is Not Normal. (Gift Article) It will take a concerted effort by every sector of our society to respond to Trumpism’s threat.

“What is happening now is not normal politics. We’re seeing an assault on the fundamental institutions of our civic life, things we should all swear loyalty to — Democrat, independent or Republican.

It’s time for a comprehensive national civic uprising”
