Resist the belief that you know everything about the issue already. Feminism is an actual field of study. As with any field of study, it should be entered with an absence of preconceptions. If a woman has strong feelings about women's issues, it doesn't mean she spends all of her time sharpening her castration tools. Talk to women about what's important to them. As you learn more, you'll understand more, in the same way that a budding engineer might gradually grow to understand a complex blueprint. If your first instinct when you hear the word “feminist” is to say “those man-haters want equality, but they still want me to pay for everything, hurf durf!” then you currently have as accurate an understanding of feminism as a confectioner would have of a Titan II missile schematic. You know those congressmen who say that Grand Theft Auto IV is a “crime simulator” that is “training new felons?” That's you, and feminism.
