Did you see the article claiming Hunter Biden's laptop wasn't really Hunter Biden's laptop, but rather had "all the classic earmarks of a Russian information operation"? If stories like this, run by fake news sites such as NPR or NYT, popped up in your social media feed about the 2020 U.S. presidential election, they probably came from a tiny group of people with a massive impact.
> get enough people vaccinated that community spread stops being a thing
The problem with this plan is that vaccinated people still catch and spread the virus. The available vaccines do not create "herd immunity" in the traditional sense.
I think the best argument for getting a vaccine now is you will be much less likely to get hospitalized (and/or die) if you catch COVID after being vaccinated. But that argument may not apply to people who already caught it, recovered and now have some natural immunity.
That's a good point. I suspect that being vaccinated reduces the likelihood of spreading it to other people somewhat, but I don't know if the data supports that.
It's evolved beyond that definition to encompass people imitating the actions of others with the belief that those actions will grant them something. In this case, it's low status people thinking that hosting rooms and talking inanely will increase their status when the reality is those activities are merely ways to show status, not gain it.
Similarly, "cargo-culting" can be applied to a piece of code or script everyone copies and reuses without actually knowing how it works and then being confused when they've effectively built a wooden airplane and no goods have arrived.
