“Anyone can be sued for anything at any time. If you live in fear of that, you are a sheep”
And if you shove your hand into a grinder you are a fool.
I don’t know what the store owner’s profits are, or what the particular burdens are to sell guns, and whether that ability is a ‘right’ or a ‘privilege’, but law suits are expensive things, and administrative law is a tyrannical thing, and this guy is courting the loss of his business from a couple of angles.
As for ‘wimp’, ‘fear’ and so on, the Celts thought that body armor was an indicator of cowardice. Romans did not. The results which followed demonstrated some doctrinal deficiencies on the part of the Gauls. I am with Patton. The point of the exercise is to make the other son of a bitch die for his country, not throw oneself on a theatrical sword.
Patton also knew that someone had to stand out there in the face of strafing planes and shoot at them with a pistol - to show leadership, bravery, courage.
I fully expect that this business owner, unlike your elitist atitude, knows full well the calculation he has made and has made it anyway. Step to the rear. Make way for the leaders.
