“Imagine a substance that is relatively new in the public square, but by now so ubiquitous in your society that a great many people find its presence unremarkable. Day in and day out, your own encounters with this substance, whether direct or indirect, are legion. Your exposure is so constant that it rarely even occurs to you to wonder what life might be like without it.

In fact, so common is this substance that you take the status quo for granted, though you’re aware that certain people disagree. A noisy minority of Americans firmly opposes its consumption, and these neo-Puritans try routinely to alert the public to what they claim to be its dangers and risks. Despite this occasional resistance, however, you — like many other people of your time — continue to regard this substance with relative equanimity. You may or may not consume the thing yourself, but even if you don’t, you can’t much see the point of interfering with anyone else’s doing it. Why bother? After all, that particular genie’s out of the bottle.” — Mary Eberstadt (Policy Review).
