I don't care if masks work or not. If you want to change someone's mind, keep it really simple, and to one point. Don't argue about masks, don't bother making arguments about vaccines, just simply state that the disease is not very deadly, and has a mortality rate of 3 people out of 10,000 if you are under 50 years of age. It doesn't matter whether masks work or not It doesn't matter whether the vaccine is safe or dangerous. What matters is that the disease itself is basically a non-issue to start with.
