Here's what the Second Amendment says:
A well regulated Militia, being necessary to the security of a free State, the right of the people to keep and bear Arms, shall not be infringed.
I do not see where that provides for shoppers terrified to to to the grocery store without toting a gun along. Those people make me nervous, because fearful people, like fearful animals, are dangerous.
Fortunately, where I live, we're mostly pretty civilized. Masking, polite social distancing, no guns in inappropriate places.
