While we're sharing anecdotes, I'm not a WV Native so I'm not a true hillbilly. I was born in PA and lived in a suburb of Cleveland when I was young.
And you know what? That suburb in your state was, easily, the most racist environment I've ever had the privilege to experience.
With the anecdotes out of the way, your thinking on this is so far out of whack it's not a wonder you see racists everywhere you turn. If what you say is true, borders are racist constructs, because borders keep 'the other' out. That's why we have borders, right?
To keep people from other places, that don't share our culture and values, out. You should go visit Western Europe and see how the no border lunacy is working out.
