The Trump administration is excusing murder by ICE using the same lies as those told by Maduro’s regime. These lies are part of the logic of death squads. Govt controls the story & the next murder is easier. And suddenly this is normal and people simply disappear.

EXCLUSIVE: Leaked WhatsApp messages show Labour MPs urging govt to leave X, arguing that it should "show direction to others in the UK"

The MPs said X owner Elon Musk is "fascist" and that the platform's AI tool, Grok, had put "children in harm's way"

"What will I do when they start murdering civilians & blatantly lying about it?"
I think a lot of people will, somewhere deep inside, be surprised to discover their actual answer to this question. Mostly 'free speech' campaigners, terminally online 'classical liberals' & self-styled 'libertarians'.

If a website appeared overnight that gave hundreds of millions of users the opportunity to create CSAM you'd expect governments to shut it down quickly, so the question is why X gets a pass when it's done just that?

You and your wife drop your 6-year-old off at school. You just moved here. You see ICE terrorizing your new neighbors. You film them, as is your legal right. Your wife complies with orders. She is then shot in the head. You still have to pick up your child later today.

This could be you.
Distraught woman says ICE killed her wife in video after deadly Minneapolis shooting "They killed my wife," the distraught woman says, adding, "They shot her in the head." An ICE agent shot and killed a 37-year-old woman who was driving an SUV in Minneapolis on Wednesday. / Screenshot/@Breaking911 "They killed my wife. I don't know what to do," the woman says through sobs in the footage, with a damaged SUV visible in the distance behind her. "We stopped to videotape, and they shot her in the head," the woman cries. "We have a six-year-old at school," she says, almost unable to breathe, as a chaotic scene in which federal officers prevented at least one doctor who was on the scene from assisting the shot victim unfolds. "We're new here," the distraught woman says in despair.

I don't know who needs to hear this, but cops are not allowed to shoot people just because you didn't do what they said.

That is called murder when they do that.

Some cops are working hard to convince people otherwise.

If the UK government had a Culture Secretary, that person would be in a position to take a view about whether child porn on demand was a good thing, or a bad thing. thecritic.co.uk/brin...
Or there’s X, the website formerly known as Twitter. Its owner is committed to removing the government, and seems keen to encourage violence on Britain’s streets. Now its 2026 update lets users create what are politely called “sexualised images” of anyone, including children. A Secretary of State for Culture, if Britain had one, could take a view on whether this was a welcome development. They could, if they had been appointed and went into work every day, offer Starmer advice on whether X should be one of the government’s main channels of communication, effectively supporting a site that produces on-demand pornography of real people including, let’s say it again, children.

Even in 2026, this should still be shocking. It is. www.whitehouse.gov/j6/
The Democrats masterfully reversed reality after January 6, branding peaceful patriotic protesters as “insurrectionists” and framing the event as a violent coup attempt orchestrated by Trump—despite no evidence of armed rebellion or intent to overthrow the government. In truth, it was the Democrats who staged the real insurrection by certifying a fraud-ridden election, ignoring widespread irregularities, and weaponizing federal agencies to hunt down dissenters, all while Pelosi’s own security lapses invited the chaos they later exploited to seize and consolidate power. This gaslighting narrative allowed them to persecute innocent Americans, silence opposition, and distract from their own role in undermining democracy.

Trump’s apologists defend his actions on Jan. 6, 2021 by claiming he merely told the mob to march “peacefully and patriotically.”

The truth: Trump’s speech writers added that phrase. It’s entirely inconsistent with the rest of his incendiary speech, which included about 20 uses of “fight.”

Matt Walsh tweeted last year: "We've spent the last 25 years bringing "freedom" and "democracy" to countries around the globe while our own country has been systematically invaded and now our largest cities are run by foreigners and communists. If you want to know why I'm so avowedly non-interventionist, this is why." Then he tweeted today: ""This is a war for oil!!!!!" First of all, the "war" lasted like 90 minutes. Second, going to war to secure vital resources for your own people is totally legitimate. Why should we allow some third world communist shithole to control trillions of dollars worth of oil?" Laura Loomer tweeted last year: "I’m America First, I don’t support “Regime Change”. I went on @Bannons_WarRoom to talk about Chinese aggression in Venezuela and why we need to designate the Muslim Brotherhood as a foreign Islamic terrorist organization." Then she tweeted yesterday: "Maduro has arrived at the DEA office in Manhattan. He was transported in an armored motorcade after being transported in a blindfold via helicopter & then by plane to New York after his compound in Caracas was raided by US Special Forces. Proud to be an American today! USA 🇺🇸" Catturd tweeted last year: "Name one U.S. inspired regime change that hasn’t ended in absolute disaster." Then he tweeted yesterday: "Venezuela is now more free than New York City." Will Chamberlain tweeted last year: "The Republican Party is no longer the party of regime change and endless wars If you want to be its standard-bearer that is a non-negotiable position" Then he tweeted yesterday: "I can think of few better uses of my tax dollars than black-bagging the head of a foreign narco-trafficking organization that enriches itself by addicting and poisoning my fellow Americans"
