UKian here to lecture you on how nuts you are: I'm sure there are cases like yours, where you will retreat from a situation because you have a deadly weapon hidden on you. I've known people who carried weapons and who would generally try to avoid danger. But I'm 100% positive that's not the norm, and most people who feel the need to have a gun would react less predictably. I've not lived in the US, but the impression I get from media is that there are a lot of gun owners who haven't trained with them or who are "muh freedoms" idiots.
