Sorry, JC. This is bogus.Fauci has initials and told us on March 8 - "wearing a mask might make people feel a little bit better and it might even block a droplet" but then a month later is telling us that you must wear masks. Did he get some additional initials behind his name during that month that all of a sudden gave him some new insight?
It's about the data, not about who said it.
Fauci had lots of data of varying quality streaming in during the early phases of the pandemic and was doing his best to try to develop a public health response. The fact that he changed his recommendation when he had more information (and when PPE had become more readily available) indicates to me that he is following respected scientific approach and being willing to change his recommendation as information demanded.
...and as far as initials after someone's name goes, I prefer to accept the opinions of someone who is educated in the subject on which they speak over someone who is not, absent any other evidence of who may be right. So, yes, additional initials are important here.
