I’ve seen open carry here in Texas. I never had a problem with it.
When I was training Americans in Nashville, there were plenty of times I saw open carry. I always told them it’s good that they are exercising their rights. I myself would prefer concealed anyways to maintain the surprise, but open does have it benefits too.
I have witnessed open carry in KY many times. Walmart, Kroger, Subway etc... No one pays it any mind in the mountains. In Lexington or Louisville some snowflakes would probably piss themselves.
Walmart and Kroger will find out the same way Little Dicks and Gillette did when they dove head first into leftist politics, there are consequences for their actions.
