Here is how I see it
Open carry is not for everyone. If you're unwilling to make your point to other people as to why you're carrying out in the open, then don't open carry. If you fear you might be a first target for a crazy guy, don't open carry. If you're concerned about scaring other people, don't open carry.
I've never heard of any incident involving a citizen that is open carrying getting shot first during a robbery.
I support both CC and OC equally, and encourage other law abiding citizens to exercise the right to carry, given their state allows it, and seek training if your state law requires it. I personally CC more due to the long winters and short summers here in Alaska, but during the summer I like to open carry a little more.
I don't tell other people that they should carry openly or concealed, or carry at all for that matter. It is a personal choice, and a great personal responsibility. I choose to carry the way I do for my own reasons.
