All right, let's do this one last time.
My name is David Clark. I was bitten by a radioactive crinoid, and for 13 years I was on the bird site as clarkeocrinus.
I'm pretty sure you know the rest.

Scrolling through the photos of Pam Bondi's "Minnesota rioters," it's just hero after hero. Every photo includes a cowardly DHS agent with their back to the camera.
Bondi thinks she's going to win the propaganda war with this shit, but it's never been more clear that they're losing.

The 2025 shootings of Minnesota legislators were treated far too lightly. Media and the public moved on too fast without grasping the seriousness of assassination. These are life and death issues, not just differences of opinion the USA is working out. The reactionary right is ready to kill.

Until the actual killers face justice, every single person who works for DHS can be presumed to be a murderer. If they want anonymity, they get collective responsibility.

Again and again, President Trump has tried to stay focused on domestic economic uncertainty, a key issue in this year's midterm elections.
Again and again, Trump's attention has drifted elsewhere — and away from the concerns of his restive base.

This is why we had Jim Crow instead of truth and reconciliation after slavery ended. People are so quick to absolve anyone who pays lip service to changing their mind about human rights violations instead of letting them live with the social consequences of their words
Bluesky idea: if people who didn't agree with you change their opinions so that they do agree with you, why not be happy that you are making progress - rather than complaining that they are "only just catching up"?
