Suit yourself. I support open carry for those who want it.
I also know there is a lot of the "keep it hidden so it doesn't scare the sheep" in the firearms community that people from Massad Ayoub on down have tried to justify as "Tactically sound".
I still don't understand how making yourself look like an easy mark protects you from predators.
We can "what if" until the cows come home but it won't change human nature one iota.
