Naturally, authorities turn to censorship systems that would justify total surveillance and strike fear into people. But there are other ways to teach young men that women generally don't enjoy force or violence.

Here's an idea: sell cute signs with slogans such as, "I don't like being slapped, spit on, gagged or choked. How about asking what I do like?" Women could put those up in their bedrooms, to be seen by their male lovers. For men who have been taught wrong, and were never informed it was wrong, one occasion could set them straight.
