Post from Paul Rosenberg that says: give it a rest dude. i've had queer friends since i was at least 5. i wrote under a gay black persona in a zine as a teen in the 60s. i've been the only straight dude in a queer performance art space & teased for it by the performer who i was there to support. i REALLY don't have time for yr BS.

The first image is from Trump's post today and the second is a post from a Christian nationalist pastor from November 2023.
Trump's Truth Social post: I love the smell of deportations in the morning... Chicago about to find out why it's called the department of WAR. LLM-generated image with Trump in a cavalry hat, military helicopters invading Chicago, flames, and the words Chipocalypse now. Post from Christian nationalist Ben Zeisloft: "GM. We must retake Ohio. Pray for the church in Ohio, and labor to rout the evil of child sacrifice in your state." LLM-generated picture with military helicopters, tanks, and crusaders on horses, marching through the streets of Ohio.

"eradicate practices that devalue and demean the Christian faith" is genocidal rhetoric. I also am not sure what it refers to practically in regards to *foreign policy*. Is it anti-Muslim immigration policy? Mandating Christian prayer in the office? Apocalyptic expectations about Israel?
Twitter post of the department of state: "Our nation was founded on the recognition that moral virtue and a steadfast faith are necessary preconditions of freedom. Yet under the Biden administration, U.S. foreign policy belittled Christianity and weaponized government against faith. That era has ended. Under POTUS's leadership, the State Department will eradicate practices that devalue and demean the Christian faith."

Isn’t the aesthetic of this mini park a bit faerie like? BTW this is in Odense where H.C. Andersen lived.
A ring-shaped bench. Wildflowers behind it. Short grass with train tracks running through it. Background has trees and buildings. Circular benches like toadstools, and a circular garden in a gravel yard, surrounded by hedges and wildflowers.

Wrocław has accepted 100,000 Ukrainians since the Russian invasion. Today I ate some Ukrainian food, a potato cake with chicken and cheese folded inside, covered with mushroom sauce. I also had Ukrainian kombucha.

Many Copenhagen streets are closed today for a cycling events. At the corners of the bridge you can see the flag of Kalaallit Nunaat (Greenland) but the one on the right is upside down!
Bridge across an artificial lake. Movable metal fence isolates the area for the cycling route. A few pedestrians and cyclists cross the wide bridge. The flag of Greenland has a circle with a horizontal line through it and the four resulting regions colored alternating white and red.
