And it's funny, I really was waiting for the cops to show up because one of the Dropboxers had called them. Their desire to avoid having any real interaction with these kids is so painfully obvious that it makes me embarrassed for them.
As far as your hypothetical, it's just that: hypothetical, as is your perception of my hypothetical biases. It's actually hilarious, because in the hypothetical my mind conjures up, I'm sure if we met in some real-life context you would end up calling me a nazi.
FWIW, when I was younger, I knew and hung around with people who are just like the Dropboxers, and was probably like them in many ways. I've gotten to know and work with a lot of different kinds of people since then, so now I would intuitively know a better way to handle this situation than these guys did. Step 1 is to recognize that they are valuable human beings and neighbors. That's where this exchange broke down, so no need to go on to subsequent steps till we get that part right.
They grew there, we flew there.
Localism isn't good either, but a bit of respect and give and take for people who, let's face it, will soon be pushed out of their neibourhoods to make way for tech workers, would be nice.
