I agree that we should pity them rather than argue with them. The worst part, though, is how much they spread false information. Some anti-vaxxers still think covid-19 is nothing worse than the flu, when in fact Covid-19 has killed 4.8 million people (globally) in 20 months, while influenza kills around 200,000-600,000 people globally.
And how can this be a global hoax when it should not be feasibly possible. China and America treat covid-19 with the same level of concern. And no government, in their right mind, would lock down their country or state for any reason other than health. Its just mind-boggling!
