The assumption that Somalis, who obviously have built their own lives, businesses, and families need white help is just disgusting, naked racism.
These are the values of so much of Twitter's pseudointellectual class.

4) And they STILL haven’t released the Epstein files.
Of the biggest scandals in US history just this week, I think I’d rank them:
1) Federal paramilitaries invade US city based on racist lies, murder US citizens
2) Slush fund for the president from stolen foreign resources held in Qatar
3) Whatever FBI and DNI are doing re: 2020 election in Georgia

Nice article from @nattyover.bsky.social about the state of particle physics as a field. It’s historically been perhaps the highest prestige and most prominent subfield of physics but there are genuine worries about the path forward, as Natalie clearly lays out. 🧪

Pretti clearly did not brandish his gun. Which means the government is saying he was killed for legally exercising his right to carry.
It’s as clear-cut a violation of the Second Amendment as I can possibly imagine. And we’re about to see the bulk of the gun rights crowd defend his murder.

So they don't really give a fuck about immigration. They just want to establish dominance over a blue state. They don't care how.
WTF: Bondi sent Minnesota officials a letter today saying ICE would leave the state if Minnesota turns over its voter files to the Trump Administration.

To further clarify what I'm talking about here, the modern 2A cult has always hinged on this idea that every armed citizen is part of some crowdsourced militia that is ready to stand against a tyrannical government.
This is a lie, and your guns will not work for that purpose.

If you're not shouting "Abolish ICE, arrest the murderers, hold trials," you're normalizing domestic terrorism at the hands of the trump government at this point.
Abolish ICE is the moderate position and the absolute bare minimum.

ICE just murdered another American in broad daylight. Congress cannot fund without significant reforms an agency engaged in this level of lawlessness. But that shouldn't stop the rest of the federal budget from passing. The Senate should strip DHS funding out and pass everything else

If anyone expects anything to change at this point, it’s not going to happen without changes across the board and that includes Chuck Schumer. We have real Democrats in the Senate. They have the power to change leadership at any time, and that needs to happen immediately.

If ICE truly were targeting "the worst of the worst" and not, you know, deliberately brutalizing innocent families with children, they'd rush to correct all the stories like this one, apologizing and insisting it's not what they're really doing.
They don't because this is deliberate. This is it.

The parents of a 7 year old, all of whom are in the process of applying for asylum, took their daughter to the ER when her nose wouldn't stop bleeding. ICE picked them up near the hospital and they are now in detention in Texas, presumably awaiting deportation. www.oregonlive.com/portland/202...

You get a general strike—on the rare occasions you do—by the long slow slog of building organizing power with those around you in response to local conditions.
