" Anybody who forays outside the “Overton window” faces a rocky road. He or she will quickly be branded as “unrealistic” or “unreasonable” by the media, the fearsome gatekeepers of the window. Television, for example, offers little time or space to present fundamentally different opinions. Instead, talk shows feed us an endless merry-go-round of the same people saying the same things. And yet, despite all this, a society can change completely in a few decades. The Overton window can shift. A classic strategy for achieving this is to proclaim ideas so shocking and subversive that anything less radical suddenly sounds sensible. In other words, to make the radical reasonable, you merely have to stretch the bounds of the radical. "
