Bullshit.

You don't have to go all hyperbolic to make the point that asymptomatic spread is not a boogeyman. There is evidence of it.
That doesn't mean we need to freak out and set our hair on fire like the liberals want, but to say there's "no evidence" is irresponsible and somewhat demagogic of you. Meh. Shaming people for wearing masks is just as bad as shaming them for not wearing masks. I'm damn well making sure to wear a mask around my 90 year old parents even though I don't think I have Kung Flu. Only a fucking moron wouldn't.

Epidemiologic Evidence Most reports of presymptomatic (9–12), asymptomatic (13–15), or a combination of presymptomatic or asymptomatic SARS-CoV-2 transmission (16,17) were from China (Table 1). Presymptomatic or asymptomatic primary patients were typically exposed to SARS-CoV-2 during travel from Wuhan or another city in Hubei Province, China (9–16). One couple was exposed during a mass gathering in Shanghai for the Chinese Spring Festival (17). Reported cases of infected persons who transmitted the virus to others while presymptomatic or asymptomatic have occurred within families or households (9–11,13–17), during shared meals (10,12), or during visits with hospitalized family members (9,13). An inherent confounder to these reports from China is the inability to entirely rule out alternative SARS-CoV-2 exposure in the community early in the outbreak, when transmission in the community may have been undetected.

However, cases of presymptomatic transmission have been reported from other countries before widespread community transmission occurred. A report from Germany documented infection of a German businessman after exposure to a mildly symptomatic colleague visiting from China (18). Before becoming symptomatic, this businessman exposed 2 other colleagues who subsequently received a COVID-19 diagnosis but did not have contact with the primary patient from China or any other known source. A report from Singapore described 7 COVID-19 clusters resulting from presymptomatic transmission; presymptomatic primary patients varied from persons with travel from high-incidence countries to persons exposed in the local community (19). All primary patients experienced distinct periods of initial exposure and presymptomatic close contact with secondary patients who had no other known exposure risks. The incubation periods for presymptomatic primary patients with distinct exposures ranged from 3 to 11 days; for presymptomatic primary patients with travel history to an area with active transmission, the time from last exposure to symptom onset ranged from >2 to >9 days.
