I was just invited to a social platform (WillB-one) that is largely geared towards vaccinated versus unvaccinated: see screenshot.

I find this exasperating nonsense: the claim that we were dealing with a ‘vaccine’ here is unscientific. There are no ‘vaccinated’ versus ‘unvaccinated’ at all, stop with that nonsense, especially if you are going to use it like this.
Vaccinations against colds do not exist, full stop, have never existed, will never exist. Can’t be vaccinated against, every real scientist knows, anyone who pretends otherwise is simply not right in the head,
Whoever does call this a ‘vaccine’ is already responsible for promoting the delusion that such a thing against a cold would be possible at all. There is no scientific basis for that assumption.
What we have seen during ‘corona time’ is the result of 100+ years of a lousy education system, with acceleration to plastified brains. And, of course, manipulations to make a few parasites even more obnoxiously rich.
But don’t let that be an excuse to enforce this false, unscientific reality unto us as a divide and conquer game that will only be the precursor for much much more nonsense.
