I see no reason to normalize open carry when even just owning a firearm, on its own, increases your chance to be killed by a gun for both suicide and homicide. Firearm ownership itself should not be normalized, as a matter of public health.
I get that it makes people feel safer, but it does not actually make them safer. If you don't have an obvious reason to have a firearm, like defending livestock, living in a high-risk environment, or as protection against wild animals, then you are objectively safer not owning one.
