I agree that the lock-downs were unnecessary. We would have had the same outcome with or without, just different timing. We could have protected the elderly instead of sending sick people into nursing homes, etc.
None of that has very much to do with whether wearing a mask is useful or not.
Obviously the carbon agenda is an admission that they want to destroy the economy one way or another. They will use any excuse they can.
A blanket statement asking whether wearing a mask is useful or not invites an easy answer. NO, a mask is not useful.
A mask is not useful to a person with severe asthma and the uncontrontrolable anxiety that follows or is precipitated by the mask.
A mask is not useful to a person with COPD or any pulmonary disorder where oxygen levels are already impaired.
A mask is not useful to a person with cardiac issues such as atrial fibrillation or worse where oxygen levels are compromised.
A mask is not useful to a person with immune suppression issues whether from prior illness or treatment because of the concentration of bacteria and virus inside the mask.
I'm sure some physician friends of mine can list more than 100 medical issues that require avoiding masks.
A blanket statement that a mask is useful is a bogus statement.
