- China intentionally manufactured the virus and released it (Proven false, virus wasn't engineered)
- China accidentally released the virus while collecting it (Possible, but unlikely given the virus has early evidence away from both collection point and Wuhan Lab)
- China has too many wet markets that allowed the virus to mutate enough for human jump (Current consensus working theory, but also unproven as intermediary animal has not been identified)
But all of these list China as the responsible party, so if you want to call it out as not Xenophobia or Anti-China sentiment then you'd have to show evidence the reporting showed "Joint Sino-American research lab causes..." kind of headlines. Otherwise, you point strengthens that this has at least an under current of anti-china sentiment, as the reporting has not mentioned US involvement at all.
WHO of course have a lot to answer for with regards to ignoring Taiwan because if BS geopolitics when they had the most reliable/believable/compelling evidence of the nature of SARS-Cov2
The most common lab leak hypothesis I've seen is that it was engineered during gain-of-function research and then accidentally leaked.
The fallacy is just that the only reason someone would engineer a virus would be to weaponize it. Gain-of-function research is regularly done to study and combat viruses. So just because it was engineered doesn't imply it was intentionally released.
(Yes it isn’t 100% match, but it’s 100% an ancestor... so not engineered)
Here's an article mentioning this hypothesis: https://www.washingtonpost.com/opinions/2021/02/05/coronavir...
SARS-CoV-2 has not yet been found in bats or any other animal. Relatives have been found, but relatives with key differences. It certainly could be found, and if it's correct then it'll still probably be very difficult to find due to being a needle in a haystack, but so far it hasn't been found.
I'm certainly not arguing it's true and the zoonotic origin is false (and I have no clue where to allocate the confidence values, myself), but your repeated insistence that it's "100% zoonotic" is puzzling because that hasn't even been claimed by any experts yet. The jury is still out.
Sure, the ultimate origin of the virus - tracing its full lineage - will have been from an animal no matter what. But if it were substantially modified by deliberate RNA manipulation in the lab after being collected from an animal, potentially increasing its lethality or contagiousness in the process and resulting in the pathogen we now call SARS-CoV-2, that would mean this particular virus isn't zoonotic. If true, it would totally change the discussion into one about the safety of such gain-of-function research and this particular lab.
Almost any engineered pathogen of any kind (protozoon, bacterium, virus) in any scenario will likely ultimately have been derived from something already living. But once the pathogen is experimentally modified to add, remove, or alter its functioning, it's no longer accurate to describe the modified pathogen as being zoonotic. By that logic, even engineered bioweapons would be considered zoonotic (and no one is claiming in this case it's a bioweapon; the lab leak hypothesis posits benign gain-of-function research and an accidental escape). Frankenstein's monster is no longer just some guy.
It's like saying the origin of the domestic dog is 100% natural because, look, you find its close ancestor the wolf everywhere in the wild. It omits the hypothesis that some wolves were taken and deliberately shaped and molded by humans to produce something new.
