Unfortunately, the only fact you've stated is this:
> No one cought it by having a conversation or casual contact at work or in public.
Correct. The transmission of HIV was also not understood. Nor was it even known to be a virus for quite some time, hence why it was called "the gay cancer." Part of the reason why it wasn't understood was the government's intentional apathy towards it, out of bigotry.
> Besides, COVID was initially sold as being much more deadly than actually is.
You might recall that the first wave completely depleted the availability of ventilators. In fact, this very website hosted links to DIY ventilator projects because the problem was so bad.
Who are you to decide how much death is enough death to warrant concern? If the world healthcare systems cannot keep up, it's a problem. Five million people will have died by the end of the year. No other disease in US history has ever killed as many people. Your waffling about what makes a disease worthy of concern is unnecessary: salmonella only kills 0.4% of people who contract it, but we don't argue about restaurant staff using clean cooking equipment.
