It's a euphemism for "totalitarian".

The National Center for Atmospheric Research is being dismembered.
That's like taking down your radar in wartime.
If you can't see them, the enemy planes can't come.
Right?
It's depressing, infuriating.
I've followed their data, their excellent web site, for years.

They're way way better at violence, hatred, and AI slop.
So our playing field has to be peace, love, and truth.

What gets me is, every bullet that tears into a victim of ICE or "Revolutionary Guards" or other gangs
makes a profit for weapons dealers.

This is 10th-grader Arnoldo Bazan.

A citizen.

Immigration agents grabbed him and put him in a chokehold.

"We're from the United States bro!' he screamed.

Agents took and sold his phone

And when he finally got home hours later, his shirt was ripped, he neck had angry, red welts, and he sobbed.

What Would Republicans Do? If a repugnant cabal of predators and perverts beats you in critical elections, their tactics are worth studying. And, in some cases, emulating.

Do you know who Willie Horton is? What about Laken Riley? How is it that you came to know these things?

Ok, now. Without googling, how many Jan 6 rioters have recidivated? Been charged with violent or child-sex crimes? What are their names? Who were their victims?

More on the disparity here.
