I think you should manage your health and safety first and those closest to you.
You're not helping by inflicting harm on yourself and those around you. If you want to canvas for the other side, donate, volunteer, great. But these people are obsessed and inflict a lot of damage on themselves for no good purpose.
Most people empathize to those that are infected with a virus. It's often out of their control. You can only offer them help and suggest they touch grass once in a while. But you shouldn't feed into their self delusions that self harm and obsession with things out of their control is healthy and a good way to live their life
The empathy you are showing in this comment would feel a lot more genuine if you didn't reveal with your prior comment how little empathy plays into your overall worldview. I'm personally fine, you don't have to waste your time telling me how to live a better life. I was just trying to explain to you what you were seemingly misunderstanding about your fellow humans.
