Because facts are still subjective as much as we like to think that they are.
Because lets take the National Geographic Article which states:
In other words, between 1 and 10 in 100,000 people who get the flu will die, but between 500 and 1,000 in 100,000 people who get COVID-19 will pass away.
Which gives Covid on this basis a mortality rate of between 0.5-1%
Some will read that and think oh gosh that is a lot of people this is very serious we must do all we can to stop it
And others will read that and say well actually that isnt a huge amount why are we bothering.
And that is really the most dangerous thing about this it has always been Schrodinger virus because it is both. It is far more dangerous that normal flu but isnt anything like as dangerous as Bird Flu/Ebola etc.
It has a high enough mortality rate for those who take it seriously to be right, it also has a low enough mortality rate for the arguments that we need to make sure we protect everything else
And that is its true danger and the reason why there is no clear way through this
