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.<p>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.
