The Ministry of Propaganda has gone all-in on several narratives readily refuted by known facts.
"Suddenly" these lies which have been repeated to the point of being tru-isms are not only not supported by evidence, but the whole narrative they have so insistently crafted has been turned on its head.
Unfortunately, their ignoring the real facts, y'know, the ones the "factcheckers" have spent the last two years denying, just keeps the narrative's inertia going, when it could have been stopped cold by simple admissions that the previous stories were wrong.
It isn't a question of credibility any more, the truth has been revealed and is spreading, and the media outlets' collective credibility isn't worth a vienna sausage tin full of dog poop.
There must be some other reason for not backing off, and that reason is becoming evident with the draconian and totalitarian behaviour of the Trudeau regime, something I fully believe those pulling the Biden puppet's strings hope to play right here in the USA.
Unfortunately, the tendrils of the Deep State/Swamp are indeed deep, and with rare exception, the GOP is failing miserably at objecting to either the narrative or the measures the Communists/Totalitarians in our own government hope to use to run roughshod over our Constitution.
When the Patriot Act was passed, in a fit of anti-terrorist fervor, with eyes looking outside our borders, few noted (as did some of us) that there were no safeguards against those measures being taken against the average American--the only 'safety' we had was one of a commonly agreed upon definition of what constituted a "terrorist".
Well, friends and neighbors, in the words of Walt Kelly, who so aptly placed his characters in the comic strip Pogo in a swamp, "We have met the enemy, and he is us."
The media are the propaganda arm of the totalitarians, whatever political party they claim.
By their fruits (actions) shall ye know them.
