> The virus that causes COVID-19 is thought to spread mainly from person to person, mainly through respiratory droplets produced when an infected person coughs, sneezes, or talks. These droplets can land in the mouths or noses of people who are nearby or possibly be inhaled into the lungs. Spread is more likely when people are in close contact with one another (within about 6 feet).

What, without evidence of it ever spreading from one person to another in a grocery store, you believe it isn't possible? Is extrapolating the knowledge of how it spreads to the possibility of encountering that situation in a grocery store not viable here? Shall we wait for evidence of spread in every single possible permutation of leaving the house before we consider such an activity potentially dangerous?

I was challenging isolation. I go grocery shopping - I think it can be done safely. But, I wouldn't do it if I lived in some red state full of pandemic deniers with huge spread rates - it's too dangerous. In my area, everyone wears masks, everyone makes sure to social distance, so it's not as much of a risk. But I acknowledge that I'm not isolated, and that was the claim that was made.
