Again, learn how to have a conversation without the condescending attitude. This is a complex issue with multiple variables and costs.
You are not automatically right because you agree with the mob. A cursory reading of history should make this obvious, but unfortunately that seems too much to ask of people nowadays. They'd rather spend their time looking down at those with the "wrong" opinion.
> You think the risk is negligible. The rest of the world does not.
The catch here is that people are really short-sighted evolved primates. While shutting down the entire world will indeed stop the virus, it is already having an innumerable number of unpredictable effects like putting millions out of work, crashing the economy, diverting resources from other medical issues, to name a few.
The statistics are pretty unconvincing so far, to me personally, in order to justify a long-term shutdown.
> This is not an abstract argument, we are watching thousands of people die from this, and we believe that community transmission comes from otherwise healthy people passing it around long before they have any symptoms at all, and those carriers need not die to cause the deaths of others.
Millions die from obesity, car accidents, war, and the regular flu every year. Where's your outrage for that? Why are you not calling for the shutdown of McDonald's? The restriction of car use? These are vastly bigger issues that are actually controllable.
As I said above: the actions being taken now will have consequences which have only just begun.
