Slate argues that internet porn prevents rape:
Similarly, psychologists have found that male subjects, immediately after watching pornography, are more likely to express misogynistic attitudes. But as professor Kendall points out, we need to be clear on what those experiments are testing: They are testing the effects of watching pornography in a controlled laboratory setting under the eyes of a researcher. The experience of viewing porn on the Internet, in the privacy of one’s own room, typically culminates in a slightly messier but far more satisfying experience—an experience that could plausibly tamp down some of the same aggressions that the pornus interruptus of the laboratory tends to stir up.
This probably won’t strike much of a chord with the “rape is not about sex” crowd, but it could be an idea for how to keep the prowling cats at bay.
