When did you switch from hating masks to loving masks? What caused your switch? Why caused you to hate them before you loved them? Was it a conspiracy?
Let's make the exceptionally charitable assumption that you are asking this question in good faith... Nobody that listened to public health experts ever "hated" masks. But initially, they didn't rush out to buy masks because the advice was to prioritise isolating the infected, social distancing for everyone else and clean hands to avoid [overestimated risk of] contact transmission, and not to rely on masks to protect…
In Asia they were using masks from the start, just like they did with the original SARS.
But with this second SARS doctors/WHO were saying that surgical masks had no effect and that Asians don't know what they're doing.
Then, masks not only had no effect, they were bad for you.
Then, all of a sudden masks were good. Cloth masks were good too. And you had doctors showing you how to make masks out of t-shirts.
Then masks were so good you had to wear them by force.
Then cloth masks had no effect. Then surgical masks had no effect. Only N95 and above were good.
It was absolute roller coaster, and with every turn (excused with “the science has changed”) doctors were hammering a nail into the coffin of public acceptance of science.
