I don't mind that THEY don't know. I'm troubled by how much of the PUBLIC doesn't get it.
I don't know how much of the public doesn't get it, although surely it is many people. Nevertheless, we have a "dinosaur media death watch" on this forum, and, if not for airports, no one, NO ONE, would be watching CNN any more. So, some people get it. Neither of these facts would be so if no one got it.
