@connellryan1 @DrLeanaWen Because she doesn't agree with your premise that personal protection (the lowest level of hazard control) is the right solution.
Given that mask mandates exist (I'd guess you are opposed but preference aside, reality is they do), might as well mandate masks that work better.
@connellryan1@DrLeanaWen，因为她不同意你的前提，即个人防护（最低级别的危险控制）是正确的解决方案。
考虑到面具授权的存在（我猜你们是反对的，但撇开偏好不谈，事实是他们确实如此），也许还不如授权面具工作得更好。
