This exception to the rule of polite social action should be used sparingly (if for no other reason than we will never get through a restaurant meal without someone hollering at someone else). If a lawmaker, for example, who favors a harsh, ill-conceived immigration bill walks into a restaurant, I would not recommend raising a rumpus (though I would not invite that person to my home).

Listen, I get it. The notion of shunning or excluding or heckling can devolve into philosophical hair-splitting as to whether someone has engaged in normal public service or whether they’ve strayed outside the bounds of decent behavior. Each to his own method of expressing disdain and fury, I suppose.

Nevertheless, it is not altogether a bad thing to show those who think they’re exempt from personal responsibility that their actions bring scorn, exclusion and rejection. If you don’t want to provoke wrath, don’t continue to work for someone whose cruel and inhumane treatment of others rivals the internment of U.S. citizens and noncitizens of Japanese descent during World War II. And yes, I’d have hollered at then-California Attorney General Earl Warren, who pushed for the roundup of people of Japanese ancestry, even American citizens.
