I love it when people ask about whether I have a license, and whether I would get in trouble, etc., etc.
One big reason I open carry is to advocate self-defense rights. By asking a question in a way that is not hostile or antagonistic, the questionerjust pasted a big sign on his forehead saying, "I am an advocacy target. Start talking to me."
So...I start advocating.
Look at it as an opportunity.
"Permit? Bless me, heavens, no. We still have some
freedom left in (insert state name here)."
"But, I see on TV all the time that you need to register it/have a permit."
"You also see all kinds of other things that aren't true. No, no permit needed. We're still allowed to defend ourselves around here. Now, if you want to carry it concealed you do need a permit but not to openly carry."
You get the idea. Edit the script to fit your state's laws.
Try it. It is quite rewarding when a person says, "I was thinking about getting a gun after that (insert last big news crime story here). Maybe I'll have another look at that."
