If you are wondering why people thought the virus was important despite the “low” death rate you only need to look at India right now. Or Italy before it. When it floods a medical system to the point of collapse things become very dangerous.
All I got to say is watching people yammer on about the 'low death rate' has convinced me that cognitive inertia and motivated reasoning are a hell of a drug.
Seriously my dad is 85. Death rate in his age group is not 'low'. These kinds of people simply refuse to consider the implications.
