TWJ, I linked a Wikipedia article there because there isn't exactly a paper that covers standard terminology for this stuff. Or at least, if there is, it's old and moldy and gnawed by rats and I wouldn't be able to find it.
And if you note the wording, I never claimed to not be a layperson -- just not one who's hung up on ordinary stuff. (That said, I do in fact know more than the average person on this and many other subjects. Don't let me try to diagnose someone or develop a treatment for them, but I know, say, science-communicator levels. We've spoken enough that I think you're aware of that being true.)
This /specific/ thing is fearmongering. Syncytia are diagnostic for diseases but have almost no relationship to how dangerous or scary a disease /is/. They rarely have any causal relationship to symptoms. They are almost /purely/ a diagnostic criterion. It sounds scary but it affects /nothing/.
Emphasizing that COVID is the modern era's Black Death is not fearmongering. I admit that I was wrong about that -- check the front of the thread, I said some dumb shit there.
But syncytia aren't weird. They aren't scary. The average person pre-COVID probably had some floating around their system at any given time. Even now at least some people probably have some holdovers from past illnesses. Syncytia aren't inherently dangerous, they're just funky. People have this idea from bad sci-fi movie graphical renders that if any cell changes in shape it's like the T-virus in Resident Evil or some shit. That's what I want to stop, because if people start also connecting the idea of syncytia to COVID, then you have people responding to totally harmless shit as if it's COVID tier. I don't think there's ever going back to normal after this, but if there is, it would suck to lose it again simply because some dipshit starts a meme about literally just the regular old goddamn common cold.
Am I making sense now?
