If a Jehovah's Witness comes to your door, do you consider engaging them in complex and heated debate about how they are brainwashed members of a fabricated cult labouring under a form of mass delusion... or do you simply politely say, "no thank you", and close the door?
Honestly, we will all save ourselves so much mental and emotional energy if we realise it's the same with Branch Covidians. There's no amount of reasoning that can be done with them to coax them back into reality, since, as the saying goes, you can't reason someone out of a position they didn't reason themselves into.
I read a lot of comments from these people on my "normie" friends' pages, and it is absolutely, irrefutably clear they are far too deep inside a mass cult delusion to respond to any kind of reason. Ironically, they believe the same thing about us, so there is no way these two camps can ever have any kind of productive interaction or debate.
If they haven't realised by now, when they have access to all the information ever made available to mankind on a little device in their pocket, that they are living through the most monumental hoax ever perpetrated on the population; if it doesn't ring any alarm bells for them that ultra-wealthy elites openly committed to depopulation are prioritising the old, the disabled, and the sick for "vaccination" (whilst also slapping them all with DNRs) - there's really nothing more we can do to open their eyes.
To follow the Jehovah's Witness analogy, please consider this salutary tale from the 1970s. It was a well-known fact amongst the Jehovah's Witness community at the time that the world was going to end in 1975. JW communities across the world were preparing for it, and for their inevitable ascension to heaven. They had been informed of the cosmic certainty of this event by their elders and betters - the experts - and there was not a sliver of doubt in the collective JW psyche that it was true.
When 1975 came and went without apocalyptic event, one would assume, naturally, the Jehovah's Witnesses would realise they'd been monumentally misled, that they'd been inducted into a fantasy illusion conjured up by a cult, and they would dispense with their beliefs accordingly.
They didn't. They doubled down on them even harder and the Jehovah's Witness movement remains robust around the world to this day.
That's human nature when it is under mind-control and brainwashing, so honestly, I promise you: we will save ourselves so much time, stress and blood pressure points if, when presented with ardent pro-vaxxers and plague enthusiasts, we simply smile, politely say, "no thank you", and close the door.
That's not to say, don't keep putting information out there. Do. Definitely do. But only they can do the work to de-programme themselves; it has to come from them.
I've read several accounts of people who have successfully untangled themselves from cults, and this never results from well-meaning friends and family telling them they are in a cult (this just makes them defensive and more loyal to the cult); it comes from a realisation inside them. So, put the information out there, and let people find it for themselves.
Unless and until they do, smile, politely show them the door, and put their propaganda pamphlets (Guardian etc.) straight in the bin. Your BP readings and long-suffering liver will be very pleased you did
