It is a NPC-media-believer-vs-think-for-yourself-split.The country is deeply divided on this issue, but it's not so much a left-vs-right split as a young-and-healthy-vs-old-and-sick split.
Flu viruses can have nasty consequences. Some say that because in a few regions in Europe, where the population is very old, and the healthcare system (including hospitals) is not that good, hospitals were "overwhelmed", that this coronavirus is some sort of really bad virus, which is bullshit.I met a 49-year-old white female nurse, also type A, who got very sick with Covid and still had tightness in her chest months later.

(This is not an exhaustive list)
There have been many flu "pandemics", the flu can have some rather nasty symptoms. But nobody who is not severely overweight, extremely old, has pre-existing conditions, or is a combination of these, is at risk.
My question to those that believe in the hysteria (you, in this case) is always why the scared people cannot just wear a FFP3 mask. That filters nearly 100% of bacteria and viruses from the air you are breathing. This totally obliterates the theory that the lockdown is about public health. If people could just wear these masks, and "protect" themselves from this flu virus that way, then the stupid justifications for a mask mandate ("protect others" or whatever) are just that, stupid justifications for a useless (for its stated purposes) policy. Closing off businesses has nothing to do with a virus, in general, but especially if people can just wear masks that filter nearly 100% of viruses.
Even if this flu virus was in any way more dangerous than other flu viruses, doing a lockdown and mandating masks is a ridiculous infringement on people's rights that is wrong. There is no virus because of which you should do a lockdown (and never before in history was a lockdown implemented for public health reasons). Not only because there is nothing that can justify that, but also because it has been proven by SCIENCE! itself that they are useless in slowing the spread of the flu, and in fact increase deaths.
