We Americans are easily terrified. It just takes a little eyebrow-waggling to suggest that the criminals are easily identified by the color of their skin, so that you're safe from any tactics used to suppress them.

We used to think of ourselves as gradually getting better. Turns out that all that accomplished was to encourage resentment, and we finally got tired of pretending otherwise. I dunno if we can ever get back the illusion of improvement, since it will be clear for a very long time just how powerful the urge to cower is. I hope it's soon enough for you to come visit some day, because we do also have a lot of virtues, but for the moment it's not safe for the inhabitants, much less the strangers.
