The big misunderstanding with the vaccines is that they prevent or reduce significance of the disease Covid-19. What was, very intentionally, taken for granted was that preventing the disease would thus prevent the transmission of the pathogen SARS‑CoV‑2 and thus stop the Covid-19 epidemic.
That is not the case and it was known back in 2022. Herd immunity was never possible with it.
With that said, COVID-19 is an incredibly versatile disease that can affect every organ in your body including your brain, immune system, heart etc. Getting the vaccine and avoiding getting sick is critical to your long term health and while it doesn't stop transmission it can slow it. Especially when combined with other tools, like masks, quarantining, etc.
A prerequisite to getting into a position where one is "capable of closing the valve" is to prove, beyond any doubt, that they are not a person who could ever dream of closing that valve. Even a little bit.
You are being one of those "ignore the flesh stripping blast" as you tell others that "throwing suspicion" is "not relevant". Motherfucker we've been throwing a lot more than just suspicion at them for 50+ years and they won't do shit. I'm glad you've got enough bodies between you and that nozzle so that the level of inaction is irrelevant to you, but that's not true for your shields.
