What You Can’t Say

Back in the era of terms like “well-adjusted,” the idea seemed to be that there was something wrong with you if you thought things you didn’t dare say out loud. One way to find these ideas is simply to look at things people do say, and get in trouble for. “Blasphemy”, “sacrilege”, and “heresy” were such labels for a good part of western history, as in more recent times “indecent”, “improper”, and “unamerican” have been.
