People offering their own science that "masks work", for example, were shouted down by the same people who later demanded their use.
Mentioning the scientific and logical flaws with Daszak's Lancet paper, or discussing the lab leak theory, got your posts deleted. Many legit scientists received death threats after speaking of them, thanks to the media's coverage of those topics.
Where was the debate on those topics? Not on social media, where lab leak discussion was censored. Not on corporate news. Not in the NYT or WaPo, at least not for the first 20 months or so.
This all isn't as simple as you seem to think. The science is not as clear as is claimed. The messaging is inexcusably bad. The trials are hidden to protect us from "misinterpretation". The contracts are secret, the analysis is fragmented.
For a current example, the scientific basis and the cost/benefit analysis for vaccinating under 14 year olds is incredibly suspect. Out of 1 million Irish children, one under the age of 14 has died from Corona in all this time - one child. Yet leaky vaccines with rapidly fading effectiveness are being pushed on them by state agencies.
The only reasoning given - trust the professionals. Trust the science. There's no debate on it, no dissenting view tolerated. Those with a different view can't show their evidence or their reasoning - they're smeared and vilified, called right-wing, Russian agents, Trumpists, morons, plague rats.
Meanwhile, vulnerable populations such as the elderly and sick in poor countries that can't afford the vaccines are watching us put the fourth shot into young and middle aged healthy people. It's profoundly sick - and not really very scientific, if preventing novel outbreaks and death is the goal.
