I don't want to go to some restaurant, club, store, theater, park, or other places open to general society, only to find out when it is too late, that I was next to some stranger with a loaded firearm and I was not warned. If someone like that is in the same aisle as me in a supermarket, I just might move to another aisle. If in a restaurant, I might ask to be seated elsewhere.
Durable solid digestive waste.
You don't get to deny other people their essential rights, just because you don't want to be around people exercising those rights.
Your complaint here has no more legitimacy than someone complaining that he doesn't want to to go to some restaurant, club, store, theater, park, or other places open to general society, only to find out when it is too late, that I was next to some stranger who happens to adhere to a religion or political ideology that you find disagreeable, or who has some ethnic ancestry that you don't like.
Nobody is under any obligation to give up any of their rights, just so that paranoid cretins such as yourself can feel comfortable in public.
