A few flaws with this argument:

1. We don’t know that the virus was not transmitted to other places in addition to the Wuhan Seafood Market.
2. Even if it was transmitted solely at the seafood market, it doesn’t take any wild theories about how it was only transmitted there and in no other nearby locations. It would just have to be transported there by a human, and transmitted there. A contaminated lab-worker riding their bike to the market could do it. A mad scientist carrying a spray can full of virus particles could do it too. A lab-leak in another location could have infected one person, who then infected other people at the market. None of these explanations are inconsistent with the fact that the market is just one place in a big bustling city.

Note that I’m not at all a proponent of the lab-leak hypothesis, I’m ok to admit I don’t really know all the facts about how the pandemic originated.

Regarding your debunking of the “already endemic” argument, I don’t follow your logic. What does the airport have to do with the conspiracy theory you are attempting to debunk? Why would it come from the airport to the market if it was a new deadly mutation of an endemic virus?

New idealism just dropped!

Nice. I tried out notion for a while and there were a lot of things I liked about it. I just got frustrated that it didn’t work well when internet connections are feeble, and I was kind of creeper out by how much information it would require to hand over to Notion to continue using it the way I was planning to use it.

The holocaust was a secret, it was a huge conspiracy among the German elite to carry out mass-executions of jews and others in the camps, a theory about which managed to circulate among the German population and elsewhere, but was doubted and contested. Until suddenly, allied armies liberated the camps and revealed to the world what was happening in them.

This is not to say that pogroms that happened earlier on were conspiracy theories, people knew about the pogroms that occurred as the nazis came to power, and afterwards. But the mass-extermination in camps was not widely known.

So it existed first as conspiracy and conspiracy-theory, before suddenly becoming a matter of public record.

Here’s a few:

• Sections of the CIA under the direction of CIA director Alan Dulles conspired to assassinate JFK and cover up the plot. Lee Harvey Oswald was a patsy.
• Julian Assange has been persecuted for several years and spent years in solitary confinement with the use of fabricated and trumped up charges in order to punish him for wikileaks and terrorise others who would think of doing something similar, and to create a chilling effect on journalists. The CIA also plotted to assassinate him, but the plot was not carried out.
• Major oil companies including Exxon have well known since at least the 1970’s how devastating climate change is and will be, and have used their advanced knowledge to devise a long-running propaganda campaign to deny and obfuscate the risks, while shaping politics to avoid any action on climate that would threaten their business model.

What?

What about the conspiracy to commit a military coup in Chile in the 1970’s and install a right-wing dictatorship to suppress the left?

What about the conspiracy to fabricate a cassus belli against Iraq in 2001- 2003 to invade the country under the pretext of a menace of proliferation of weapons of mass destruction?

What about mass surveillance via the internet?

What about the holocaust?

There are obviously true conspiracy theories, many are widely believed by the left and many are even public record at this point.
