Yep, Here's a response, I think you are way off base.
First off, the people you see in VA open carrying aren't doing it because they "Don't qualify for concealed carry", they do it because they want to or because of the idiotic law that forces them to either open carry in an establishment that serves alcohol or leave it in the car.
Second, where we lived in West Tennessee (and hopefully will live again in the near future, like this summer) open carry was very, very common. There were hundreds of times that I OC'ed and no one even noticed. Now, was that because it was common, partly I'm sure it was. but it was also because the majority of people live their lives in condition white and don't notice what is going on around them. A bad guy rushing into a bank to rob it isn't necessarily going to be scanning everyone for a gun. He is most likely tunneled in on the teller or the guard. It really isn't a concern. And, I already posted a link to a story that disproves your assumption that OC is tactically unsound.
I'm glad you think everyone should be able to carry as long as they are legally able. But putting qualifiers on it like no OC negates you reported belief in the second Amendment. The 2A doesn't say "...shall not be infringed. As long as it is concealed."
