That's just not true. The CDC estimates that between 10% and 70% of of cases are asymptomatic with a best estimate of 40%. https://www.cdc.gov/coronavirus/2019-ncov/hcp/planning-scena...

As we saw in Italy and New York, COVID-19 has the potential to overwhelm hospitals. Officially, almost 170,000 Americans have died. NYTimes estimates that COVID-19 already caused over 200,000 deaths by comparing against the expected number of deaths if we weren't in a pandemic. So yes, COVID-19 is a clear and present danger to our lives.
