When I was a boy there was a PSA that was broadcast with some regularity on TV. A series of photos were shown depicting men, women, and children of different ages and ethnicities. All this was done while the signs get sang “VD is for everybody.” The ’60s were an odd time to be a child.

Anyway, whatever one thinks of that long-ago commercial, as a recent essay makes clear it isn’t just VD that’s “for everybody.” Violence is a possibility for everybody as well. Those on the Left just as much as the Right.
