Unfortunately, their guaranteed predictions never come true, so the next narrative is always ready to be released once defending the previous version of The TruthTM has become untenable. That's why all the Independent ThinkersTM switch narratives at the same time - they're ultimately getting them from just a few sources.
At first we were all going to die from the vax - the narrative just fit too well with the classic "depopulation agenda". Once that didn't materialize, they tried the "be afraid of side effects" route. That one wasn't working too well, since it's too easy to realize that side effects (even excluding death) from COVID are orders of magnitude more likely & more severe than from any of the vax.
Now we shifted to "we will die from the vax later" and "infertility" - narratives which are sufficiently long term that they can be milked for a while before they have to be replaced due to actual reality disproving them.
This is the perfect example of what I like to call the "Invisible Dragon" argument. It goes like this:
I have an invisible dragon sitting next to me.
Prove it does not exist.Any argument made will result in a simple explanation that expands the powers of the invisible dragon. It doesn't displace air because it has no mass. You can't touch it because matter bends around it. And so forth and so on. The root of the problem is the person making the assertion is demanding that other people *disprove* the assertion when the responsibility for proving the assertion is that of the asserter.
The only way to handle this argument is to walk away.
Same thing here: The virus will kill people in a month by the millions. Then a year. Then 10 years. Then "infertility". Always things that can't be tested, can't be proven, and when they do fail you just slip in another argument.
It's a lot like the Millerites in the 1830's. This nutcase bunch attracted thousands by saying the world would end in 1843. When that didn't happen a "mistake" was found and it was 1844. Then it became "soon" and the sect split into the 7th day Adventists (nutcakes) and Jehovah's Witnesses. And they roll along to this day, saying the end of the world will be "soon". After all, try to prove the world "won't" end next week.....
Annoying that people still fall for this crap.
