I've been OCing for over ten years now. While I lived in Tacoma (named the most dangerous city in the PNW) I carried openly in a Serpa holster every single day. I carried all over town, and even into the Tacoma Mall a few times. I carried in convenience stores, parks, coffee shops, fast food, slow food, really any place a guy would regularly go; and that includes a coffee shop on Pacific Ave at the University. Of the thousands of hours of actual experience carrying openly, here's my take-away:
By a LARGE margin, all strangers who actually commented were completely supportive of OC. Seriously, total strangers expressing thanks or support.
I had TWO citizens who didn't appreciate OC; one merely wanted to debate firearms ownership (she believed only police and mil should own guns) and one who was attempting to get the police to come, but the dispatcher was telling her that she was not going to dispatch because no laws were being broken.
Almost ALL the people who post in forums that they prefer 'tactical surprise' or say you'll be shot first, are actually hiding the real reason they don't like OC that they're afraid or ashamed to admit. We've been around and around on those two issues and those arguments are easily refuted. They will not discuss it; they will post and run, or make some irrelevant distractor like popcorn or some such. They cannot support their position yet they'll foolishly keep making it.
I don't care one iota how someone chooses to carry, I'm as happy for the CCers as I am for the OCers. I find the discussion enlightening because of the above; people fabricating reasons why OC is bad but will not or cannot support it with any real argument.
I wrote this essay in 2009 and challenged anyone to write one refuting it. Seven years later nobody has tried.
