It is just startling how little some people know about this stuff and yet feel a need to pontificate on the topic. Imagine EVA going to a gay bar and then protests that he didn't know he was that to hook up with a guy. This is the equivalent of that.
Of course I have gone to gun round ups, get togethers, meetings, call them what you want but they met on private property and people had LOADED guns on their persons. No one was shot, knifed, or gang banged (sorry EVA) while at the gathering.
