The way to oppose hateful speech, and the implicit incitement to violence that always lies within it, is to find out who did it and punish them. Nothing else will do.

The Fresno Grizzlies, the Nationals’ Class AAA affiliate, need to find, and fire, whatever employees failed to monitor, and prevent a video on Memorial Day that placed an image of a duly-elected member of Congress alongside photos of dictators — all of them characterized as “enemies of freedom.”
