What’s up with that, you might wonder. This is a peaceful, upscale, decidedly un-diverse neighborhood. The greatest threat to suburban peace is the lone homeowner whose lawn looks a tad overgrown. There’s nothing to suggest that anyone is a racist or bigot. So again: What’s going on?

Someone came up with the label “virtue signaling” to describe the psychological impulse behind these signs. The idea is that people who put them up want to tell you how noble they are. But that doesn’t sound right. Virtue-signalers aren’t in any way in doubt about their own virtue. What they really want to do is signal how depraved others are.

It’s about vice signaling, not virtue signaling.

A couple of people on the block are Trump supporters. Those signs are likely meant for them. There’s no interaction between the two groups, and the signs are meant to keep it that way.
