“Endemic” does NOT mean “harmless”.
No, it doesn't and I do think that people understand that. Flu is endemic, flu viruses mutate and although many die from flu every year we've had to learn to live with them.
The hope is that, with many people vaccinated and others gaining a certain amount of immunity from having had Covid, we will reach the stage where we have to get back to some kind of normal even though we may have to adapt our behaviour.
It was normal at one time to board a plane without all the security checks we have now, to carry a drink with you etc but we have adapted and accept all the new security as normal.
