In Oregon, 1 in 65 girls received a transgender-related clinical diagnosis between 2016 and 2023. 1 in 240 girls received hormones. Kids in Oregon were almost 20 times more likely than kids in Mississippi to have a "gender dysphoria" diagnosis. How did this happen?

BREAKING: The American Society of Plastic Surgeons, an organization representing 92% of all board-certified plastic surgeons in the U.S., becomes the first major medical association to break from the consensus over “gender-affirming care” for minors. This is big news. 🧵

I’m surprised it was bunker busters that took out Iran’s nuke program and not clause 52(a)(iii)(13)(f) on page 14,762 of Appendix 71(d)(ii) of the Obama nuclear deal.

American pediatric gender medicine has its first major whistle blower. This was inevitable. There will be more. Jamie is courageous beyond words. The things she has seen shock the conscience. These are kids. Enough. Enough. open.substack.com/pub/bariweiss/…

Me: “What’s a ‘lunk alarm’?” Planet Fitness: “Oh, that’s when a gym bro grunts too loudly and makes women uncomfortable.” Woman: “There’s a dude in the women’s locker room and it’s making us uncomfortable.” Planet fitness: “Give me your membership card, you whiny bigot woman.”

Just stop. Nobody is buying this. Trans girls aren’t girls. They’re boys (or “biological males,” if you feel so inclined) who want to be treated as girls. You know this. I know this. Everybody knows this. And everybody knows that you know this. Have some self-respect, Jay.

Hey there. Shermichael knows exactly the language he's using. He's not some innocent rube - he's a longtime GOP strategist. Saying "boys in girls sports" was not some slight slip-up. It was denying that trans girls are girls, full stop.

I'm seeing quite a bit of comment about this, so I want to make a couple of points. I'm not owed eternal agreement from any actor who once played a character I created. The idea is as ludicrous as me checking with the boss I had when I was twenty-one for what opinions I should

Ta-Nehisi Coates’s writing on race fueled a reckoning in America. Now he wants to change the way we think about Israel and Palestine. Read our new cover story now: trib.al/14EyFWS

Wow. Justice Alito: the Cass Report finds of no evidence that gender Rx prevents suicide. Strangio: "completed suicide is thankfully and admittedly rare," the studies apply to suicidal ideation/behavior. Has the @ACLU just abandoned the "dead daughter/live son" narrative?

The casual manner in which Justice Sotomayor, a supposed feminist, spoke about girls who just “don’t want their breasts,” shows how this pseudoscientific, anti-humanistic ideology has normalized the unthinkable and seeped into every crack of our institutions.
