It's human nature to do this, why would you do something earlier than required if it takes effort? We only have a certain amount of energy / attention at our disposal.
The conspiracy theory idea I've heard is that at some point there is an intention to fake an "alien attack" in order to extend governmental power, etc.
Many people have done things like that in history (https://en.wikipedia.org/wiki/Herostratus), but that's also hard to reconcile with disguising one's role and responsibility and preventing proof of either from being established, isn't it?
It shouldn’t be considered harassing or “doxxing”, but this precedent of arbitrary labeling was set on numerous occasions. For example it was set by activists and partisans crying “doxxing” on past occasions like when journalist Andy Ngo documented the criminal activity of antifa groups in Portland or when Zero Hedge listed the public information of the Wuhan lab’s head straight from the lab’s public facing website.
Randomly made up, highly charged words like “doxxing” have no place in our discourse. We need to have fixed language if we are to reason about the world around us in a consistent and useful manner. Unfortunately these days language has itself become a political tool and battleground.
Slang happens. By planting your flag you're relegating yourself to history. Yes, these matters deserve more nuance. Yes, many of the people speaking authoritatively are in fact missing important details or fudging the facts to fit their bias. Unfortunately, that's just the state of things. I don't have a better solution cooked up, but trying to cancel is a word is just plain laughable. (Obvious exceptions are obvious)
