No because the WHO/CDC says it's wrong??
Well, the CDC/WHO has gotten it wrong on how to fight Covid on many occasions:
(1 ) Incorrect statistical gathering at the onset of the pandemic that falsely led to their conclusion that hospital resources were most at risk from Covid.
(2) Because of the error of number 1, the CDC/WHO has been more concerned (overly concerned) with saving hospital resources when fighting the pandemic rather than being concerned with saving lives.
(3) The incorrect saving of hospital resources over the saving of lives spreads the virus and kills.
(4) There has never been any program offered by the CDC/WHO to protect those most at risk from Covid exposure, the elderly and those with multi-comorbidities.
(5) The proposal of the CDC/WHO to generally lockdown everyone with a spike in Covid cases kills and disrupts economies and lives.
(6) Wearing a mask prevents hospital resources from being overly taxed because wearing a mask levels the number of Covid cases. Wearing a mask doesn't stop the spread of Covid nor does wearing a mask stop death from Covid because the Covid virus lives for 8 days, I think, on an unsanitized surface and the mask doesn't force anyone to socially distance, wearing a mask doesn't force anyone to cover the eyes, wearing a mask doesn't force anyone to cover the hands and wearing a mask doesn't force anyone to cover the ears, for examples, and all are other ways that Covid can be contracted (other than getting Covid from the Covid-sick which mask wearing only prevents).
(7) Not everyone will be adversely affected by Covid exposure but the CDC/WHO treats the fighting of Covid as if everyone were at risk from Covid.
(8) The only other time social distancing was used to fight a pandemic, during the pandemic of the Spanish Flu in the early 20th century, similar high counts of pandemic casualties occurred. 'Scientists' should've known their choice to socially distance to fight this pandemic would've created untold casualties yet marched on with social distancing anyway
because they thought hospital resources were chiefly at risk from this pandemic.
I like to throw out the misleading 'kicker' that people are overly concerned with human casualties from Covid when the CDC/WHO really isn't all that concerned with human casualties but are overly concerned with hospital resources casualties.
The CDC/WHO is dead wrong on how to fight this pandemic. What the CDC/WHO uses to fight this pandemic isn't science (neither is it logic, inference or deduction).
