The basic premise of astrology is that people who were born at certain times and places share specific, distinguishing personality characteristics. Cancers are emotional, sensitive, and domestic. Those born under the Taurus sign are stubborn, analytical and methodical—and so on. Hundreds of millions of people read their daily horoscopes, or at least know something about their sun signs. Astrology and racism share many of the same ideas. For one thing, in both cases a person is being judged by factors beyond their control. Just as people have no control over their skin color, they also have no ability to determine when and where they were born.
