When conservatives like L0m3z declare that they need no reasons for backing policies to enforce ethnic homogeneity in America, they feel the need to spontaneously fake-apologize for it to the Cato Institute. Why? Because Cato stands for reason. www.cato.org/blog/sorry-c...

“Sorry to the Cato Institute…”
Keeperman’s comment highlights how Cato has become synonymous with a reproach to the irrational identitarianism that now typifies large parts of the political spectrum.

Mullin is lying. These were not identified as "high-risk" nations, and it was not "tougher vetting" that cut entries. The absolute number of denials is LOWER now than under Biden. They just aren't even processing applications, and you owe every American sponsor an answer.

I remember when conservatives used to call liberals "snowflakes" for demanding that we care about how people's words make them feel. What's the word for demanding that we care about how people's colors make conservatives feel?

Trump has cut legal immigration from majority-Muslim countries by 96% from 21,096 legal immigrants and refugees in Dec. 2024 to 808 in Feb. 2026. Far more severe than anything in his 1st term, falling disproportionately on spouses of US citizens and skilled immigrants... www.cato.org/blog/legal-i...

Did you know that DHS is authorized by Congress to intentionally defame private individuals all day, every day and it cannot be sued for defamation? Now that you know that, does it make you more or less likely to believe anything it says? (Oh, he didn't illegally enter)

Opinion | ICE is weaponizing a baseless arrest-and-detain strategy. It’s working.

Talk constantly about how we're going to let the peaceful deportees return legally. Make it common sense by 2029. Good on the merits, and it'll prevent a border crisis when they try to get back to their families. Bonus: it really undermines all their celebrating big #s.

Under Trump, ICE has not stopped releasing immigrants from custody. It has cut releases of noncriminal immigrants, while actually releasing 50% more immigrants convicted of or charged with crimes than in December 2024. Trump's priorities are clear. www.cato.org/blog/ice-rel...

I don't know any Dems saying he shouldn't be deported after he serves his time, but MAGA would have happily deported the victim/victim's family back to Peru, including her 4-year-old daughter. Caring about the victims of immigrant crime requires more than demonizing immigrants.

Steve is writing as if showing that certain noncitizens are subject to US law is sufficient to stop the order, but Trump is asserting a much more sweeping power here: to decide if they are, indeed, subject to US law at all. Wait until he realizes what a great power that will be for his friends.

If illegal immigrants could destabilize the financial system, it shouldn't be debanking them AND deporting them. The fact that it's doing exactly what it says would cause instability proves it 1) doesn't believe its own claims or, frighteningly, 2) that it might not care!
