Exactly which decisions made have been that you deem to be in complete disregard of established medical procedures to combat respiratory illness?
I'm glad you asked. First, confining people to small spaces indoors, which is the best way to spread respiratory illness.
Recommending mask wearing for the general public, which then becomes mandated by local governments and businesses to avoid liability. Uninfected people wearing masks is worse than no good, it's like telling people to strap a germ magnet right over the two main entry points for infections.
Maybe infected people should wear them to help prevent the spread, but the problem is that they become next to useless once they become moist. Wearing the same mask all day, or for several days without constant changing out and disinfecting increases the likelihood of the uninfected becoming infected and doesn't help the infected prevent transmission at all. That is why masks need to be used strategically. Who has liability when someone contracts the virus
because they were forced to wear a mask?
I've seen people actually claim that we have to assume that everyone is infected. That's based off the notion of asymptomatic transmission. The problem with that notion is the standard for evidence supporting that claim was very poor. The claim was based on two case studies from China, as far as I could find any information. Case studies are about on par with anecdotal evidence, and two cases should never have been deemed good enough to inform a complete 180 on mask wearing recommendations.
Respiratory illnesses always drop off during times of warmer weather precisely because people are getting outside more, and the risk of spreading viruses diminishes significantly. That fact was completely ignored. Almost like none of the "experts" even knew that was a thing.
Respiratory illness spreads faster in areas of high population density, but "experts" ignored that fact when helping policy makers draft one-size-fits-all mitigation and suppression plans.
Clinics providing what were considered non-critical services have been shutdown, preventing people from getting care they need, and people with serious conditions have been reluctant to seek help due to fear of contracting covid in hospitals.
I'm sure I can think of some more points, but that's what I have off the top of my head.
